Killer Tips for Straight A in Biology

Biology learning is always cumbersome due to the lengthy chapters, structures, procedures and terms you come across in the subject. Follow these tips to get a straight A in Biology.

1. Plan study time

Biology topics introduce some new content to you. Unless you spend more hours on Biology study at home, you won’t be able to retain the classroom material in mind. So, plan your study time well on 2: 1 ratio (2 hours of home study for one class hour).

2. Make flashcards for vocabulary

You meet more vocabulary in your first year Biology classes than in a Language class. So, make it a point to make flashcards for subject terms. You will be able to remember them with ease.

3. Try to retain your knowledge of biological terms for a long period of time

Many things you learn in the class but forget once you leave the class. This can happen more in Biology classes. Review your class material instantly every day through short periods of study time. You need not take marathon sessions for this. Small units of time on regular study basis will do.

4. Participate in the class actively.

  • Read the lessons before hand.
  • Participate in the lab work with genuine interest.
  • Ask doubts when you get them.
  • Try to answer questions at the back of each chapter in your book.

5. Ask for help when necessary

When you have doubts in the subject, contact Online Biology Tutors at once for clarification and excel in your studies. Or else you may miss the chapters and it creates backlog of work for you.

Biology Homework Help is essential for students who struggle with terms and are unable to draw and learn structures and procedures. Hire an online tutor at the earliest for best results in the subject.

Difference Between DNA And RNA–A Concept To Learn Via A Biology Tutor

Both DNA and RNA carry genetic information. DNA stands for deoxyribonucleic acid and RNA stands for ribonucleic acid. Following are the differences between DNA and RNA

  1. DNA contains the sugar deoxyribose and RNA contains sugar ribose. Ribose has one more- OH group than deoxyribose.
  2. DNA is a double stranded molecule. It is a B-form double helix. It contains a long chain of nucleotides.RNA is a single strand molecule. It is A-form helix. It has shorter forms of nucleotides.
  3. DNA is stable under alkaline conditions. The C-H bonds in DNA make it stable to an extent and the body destroys the enzymes that would attack DNA.The small grooves in the helix serve as protection by providing minimal space for enzymes to attach. RNA is not stable under alkaline conditions. The O-H bond in the ribose of RNA makes the molecule more reactive than in the case of DNA. The large grooves in the molecule make it susceptible to the attack of the enzymes.RNA is produced, used, degraded and recycled in a constant manner.
  4. The functions of DNA and RNA are different.DNA has long term storage of genetic information and transfers genetic information. It transmits genetic information to make other cells and new organisms. RNA codes directly for amino acids. It is the messenger between DNA and ribosomes for making proteins.RNA   transmits genetic information in some organisms and can be the molecule for storing genetic blueprints in primitive organisms.
  5. DNA uses the bases adenine, thymine, cytosine and guanine. RNA uses the bases adenine, uracil, cytosine and guanine. The difference between uracil and thymine is that uracil does not have a methyl group on its ring.
  6. DNA replicates self.RNA is synthesized from DNA whenever there is need.
  7. While DNA is susceptible to UV damage, RNA is relatively resistant to UV damage.

Differences-between-DNA-and-RNA

An online Biology tutor can explain these differences more in detail for the benefit of Biology students.

Types of RNA

There are basically three types of RNA-mRNA, rRNA and tRNA.

  1. mRNA (Messenger RNA): mRNA transfers the genetic information from nucleus to the cytoplasm of a cell. It transcribes the genetic code from DNA into a form that can be read and used for making proteins.
  2. rRNA (Ribosomal RNA): rRNA is found in the cytoplasm of a cell where ribosomes are found.rRNA directs the translation of mRNA into proteins.
  3. tRNA (Transfer RNA):Like rRNA, tRNA is located in the cytoplasm of a cell and it is involved in the synthesis of protein.tRNA transfers or brings amino acids to the ribosome that correspond to each three –nucleotide codon of rRNA.The amino acids are joined together for processing polypeptides and proteins.

Doing assignments on types of RNA or any related topic can prove intriguing to students. They can seek Biology assignment help via virtual medium and enhance their scores in Biology assignments. Same way, doing Biology homework in tough chapters may also cause troubles to students testing their minds in the last minute. Avail Biology homework help from subject scholars and learn Biology topics with renewed interest.

Protein Denaturation-An Important Concept In Biology

Biology has many topics which unfold the truths of nature in an interesting way. Protein denaturation is one such topic which shows how denaturation of protein is found in common household activities like cooking.

What are proteins?

Proteins are found in all living beings. They are large molecules which are composed of folded amino acid chains. Every protein has its unique shape and functions as based on its shape. Proteins are like keys that fit into certain shaped locks around the body of living organisms. Proteins are required for speeding up biological processes, recognizing antibodies, providing substances, regulating physiological processes and genes, transporting substances and responding to signals inside and outside of the organism.

Protein

Denaturation of proteins

Denaturation is the process by which proteins lose their structure and stop to function. The four levels of protein structure are primary, secondary, tertiary and quaternary.

The primary structure of a protein is the sequence of amino acids that form the proteins. Every protein has a unique sequence for the amino acids. If the amino acids are not in order, proteins will not function properly.

The secondary structure of a protein describes regular repeated patterns of initial folding that are found in the protein. There are two types of folding at this level- alpha helices and beta sheets. An alpha helix is a spiral coil shape that is formed by hydrogen bonds. Beta sheets are formed when two amino acid chains align and form a flat or wrinkled area pattern.

The tertiary structure of a protein describes the shape of the protein when all the amino acids, alpha helices and beta sheets are folded into a specific structure.

The quaternary structure describes a protein which is composed of two folded amino acid chain subunits that come together to form one final protein.

What is denaturation of proteins?

Take the example of an egg. Eggs turn hard when you boil them. It is because the protein molecules start to unfold when the white egg is heated up. This process is called denaturation.

Denaturation involves changes in the primary, secondary, tertiary and quaternary structures of a protein. It happens because of the disruption of the weak noncovelant bonds that stabilize those higher orders of protein structure. Denaturation decreases the diffusion coefficient   and crystallization of proteins. It alters the surface tension, extinction coefficient and absorption spectrum.

denaturation of proteins

Stability of a protein is determined by measuring the difference between free energy of the folded and unfolded state under equilibrium condition. Most proteins have irreversible denaturation on exposure to high temperatures. Cooking food denatures proteins and makes digestion more efficient.

The three types of denaturation

  1. Temperature denaturation
  2. pH denaturation
  3. Denaturation by organic solvents

Causes for denaturation of proteins

Extremes of pH, chaotropic agents and heating are the causes of denaturation. The extent of denaturation depends upon protein type, moisture content, concentration, ionic concentration and composition.

Incorporation of air bubbles and adsorption of protein molecules to the air- liquid interface also cause denaturation of proteins. The extent of change in conformation of proteins is based on the flexibility of the proteins. Highly flexible proteins denature more readily than the rigid ones do at an air- liquid interface.

Causes for denaturation of proteinsCollege Biology courses have many more exciting topics that show up a treasure of ideas and knowledge for students who are interested in the subject. Some of them may be intriguing and as such students need expert help from online college Biology tutors who make even the challenges in the subject easy to understand with their custom made solutions and approaches.

Doing Biology is an interesting aspect of human study and it involves various unique findings that have paved way for major medical researchers, discoveries and inventions of medicines that are all useful for the health of living beings. Biochemistry, Molecular Biology and Genetics form part and parcel of Biology and are overlapping in their theories and approaches with some minute differences.

BiologyForTeachers

Following statements beautifully describe the difference between Biochemistry, Molecular Biology and Genetics.

  • Biochemists are those who study the known products of unknown genes.
  • Geneticists are those who study the known genes with unknown products.
  • Molecular biologists study the known products of known genes.

This is the essential difference between Biochemistry, Molecular Biology and Genetics.

What is Biochemistry?

Biochemistry studies the chemistry of life. It deals with proteins as building blocks of life. It studies RNA and DNA in relation to understand and describe living processes. Biochemists provide new ideas and experiments to understand how life works and they support our understanding of health and disease.

research-in-a-lab-with-three-people

What is Molecular Biology?

Molecular Biology tells us about Biology at molecular level. It discusses molecular techniques like cloning, PCR, blotting etc. It primarily concerns understanding how various cellular systems interact in terms of the way DNA, RNA and protein synthesis function.

molecular_biology

What is Genetics?

Genetics is the study of genes, heredity and genetic variation in living beings. The topics in Genetics vary as we learn more about genomes and how we are affected by our genes every day. Genetic engineering is the artificial manipulation of the genetic material of the organisms including the creation of novel genetic material. This manipulation occurs to a large extent external to organisms as in test tubes and vitro ( in glass). Genetic engineering is used to make recombinant DNA,to purposefully change nucleotide sequences and to clone DNA.

genetics

What is the difference between Biochemistry and Molecular Biology?

Biochemistry is covered with proteins, their structures and how they interact with each other. It is concerned with structure and function. Biochemists deal with shape and location of a protein which decide its function. Your eye has a certain shape and arrangement that allows it to function as an eye -this is what Biochemists discuss.

Molecular biologists, on the other hand, look at a smaller scale and deal with a lot of RNA and DNA work. They look at the atomic scale of proteins instead of macromolecular interactions of proteins. Of course, there can be some cross over between Biochemistry and Molecular Biology like Biochemists looking at atomic interactions in a binding or catalytic site and Molecular biologists looking at the larger scale structure of DNA and RNA or peptide interactions.

Biochemistry is a chemistry focused course. Molecular Biology is a Genetics focused course. Biochemistry has to do with the chemical reactions that happen within the body. Molecular Biology focuses more on the structure and the relationships between four molecules (proteins, lipids, carbohydrates and   nucleic acids) in the body. Molecular Biology can cover other topics like Microbiology and PCR whereas Biochemistry is related to things like nutrition and enzyme deficiency.

Difference between Molecular Biology and Genetics

Like Biochemistry, Molecular Biology deals with the structure and function of proteins and how genes are expressed in cells. Molecular Biology takes genes further by considering genetic approaches to things (like genetic engineering and how to approach genes). Genetics covers most of the same genetic parts of Molecular Biology and also includes a non-molecular part like evolutionary Genetics, population Genetics etc.

Molecular Biology is more like investigating and figuring out metabolic pathways. Genetic engineering is more manipulative, trying to alternate such pathways as in trying to get plants to produce more food per unit.

Learning these subjects through an online Biology tutor

It is only online Biology tutors who can hit the nail on the head with specifications about subject nuances, clarifying the bordering differences in these topics with practical examples and innovative methods for understanding.

Tips for Helping Your Children with Math Homework

Posted on by

Math Homework HelpGetting your child to do their homework can be a lot like trying to pull teeth. There may be a whole lot of resistance from the child but be patient. Learning is about improving ourselves, and even children understand that. They are always going about learning new ways to make this easier, or more intriguing or most of all, fun! So let’s approach the process from that perspective, shall we?

No Pressure

Children often feel a lot of pressure from adults and adults do not even realize when to pump the brakes a bit, but that is all a part of human nature. Children of course do need to be pressured, but in a positive way. What really works to motivate anyone is to show the short-term or long-term benefit to what it is that you are trying to accomplish. If you go in guns blazing trying to force pressure the child into learning the topic and you become frustrated, your child will in turn notice the negativity right away and begin to decide that they are being judged. They are right.
So avoid this tactic. Try to be open and understanding of their own learning process. Explain the logic of math problems in a way that will show them those benefits, how math is all around us, whether we are gauging our speed driving to school, measuring ingredients for a delicious snack or meal or counting the school supplies that we need. Specific examples really help children appreciate why we need to understand the concepts in mathematics, even at a basic level. They will be more enthused by this method and seek new ways to solve problems with more advanced math. A lot of this is just all about attitude and mentality.

Visual and Practical Models Work

Math is taught with great success in many Asian countries and many believe it is because of the way in which students learn the concepts and make the transition. It has been revealed that more visual representation matters to the student when discussing anything from simple basic addition/subtraction/multiplication/division to fractions and beyond. When they make a visual connection to the data, their brain can begin quickly deconstructing the logic behind the problem.
Ask your child to work out the problem aloud with you so you know their line of reasoning as well. This will help you understand their approach so you can teach them some new tricks. Again, be patient. The respect factor is exponentially higher with children when you are on their level and are actually helpful in their eyes. You should also work problems out aloud with them and do the same with everyday scenarios in life as you are going along your day with your kids. Explain concepts in everyday tone and language and relate it back to those school math problems they were working on.

Be Involved

It may seem obvious that you need to be involved in your child’s education, but moreover, try to be involved in their actual math problems and other studies. Make it your problem too. They will be more studious when they feel it is a group activity or game. Make it fun for them if you can by creating mini milestones like a bonus fun game for every successful problem solved or for finishing their homework. Remember how flash cards worked? The more colorful the cards the better by the way.
Being involved in all aspects of a child’s life is a great way to keep them involved in positive life activities as well. Your child will feel supported and confident knowing that their parents are there for them to help them when things get really tough. In math, when a problem is tough to understand, they may feel comfort in knowing that Mom or Dad can help guide them through it so they may understand it better. This helps a child’s confidence and self-esteem like no other.

Rewarding the Triumph

Children; just like pets, wild animals and grown adult humans; need to see the immediate benefits to the work behind learning a new skill, one that may seem mundane or useless in the form of numbers, symbols or expressions on a piece of paper or computer tablet screen.
When your child solves a problem, be sure to remember to try to challenge them to think of a way that problem can be implemented in the real world, or even better their world! When the child begins to unravel mysteries, not only will it excite and motivate them, they will be rewarded with pride and wisdom. They are never too young to understand this!

Stages Of Mitosis-An Important Study In Biology

Posted on by
Reply

Mitosis is the type of cell division by which a single cell divides into two daughter cells. It is the method by which the body provides new cells for growth or repair of aging or damaged tissues. Mitosis occurs in all somatic cells except gamete (the reproductive parts).

MitosisMitosis is a complex physical process and is divided into phases which balance with the completion of one phase and starting of the other. These phases are called Interphase, Prophase, Metaphase, Ana phase and Telophase. During all these phases, pairs of chromosomes flock, amalgamate and affix themselves to fibers which pull sister chromatids to opposite sides of the cell wall. Cytokinesis completes the cell division by dividing the cell membrane and thus daughter cells are produced.

During Interphase, the cell does not undergo division but executes all activities for life. It reads DNA which is essential for a replica cell of the parent cell during mitosis.

During Prophase, the commencement of cell division occurs. The combination of DNA and proteins (chromatin) formed in Interphase coagulates to actualize into chromosomes. The nuclear membrane formed during Interphase breaks, the chromosomes become shorter and thicker and migrate towards the opposite sides of the cell. They are bound at the centromere, interconnecting two sister chromatids and forming an X.

In ProMeta phase nucleus membrane formed in Interphase   starts dissolving and spindle fibers invade the nucleus space and proteins affix to the centomeres creating kinetochores. In Metaphase, nucleus membrane dissolves completely and spindle evolves in complete form. The fibers alienate chromosomes in an imaginary line .Anaphase is the phase of separation of chromosomes wherein the spindle fibers attached to the kinetochore distance the chromatids from each other resulting in two daughter chromosomes.

In Telophase, the chromosomes are roped off into two nuclei in daughter cells with spindle fibers disintegrating and chromosomes unwinding and a new nuclear case reforming around the daughter nuclei. Thus ends the process of mitosis.

An online Biology tutor explains such topics in a lively manner and invites the attention of students  towards more interesting topics in Biology.
