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

Posted on by

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.

Thus learning topics like protein denaturation or other such ones with the guidance of online tutors improves the scores of students with better insights.

What Is The Difference Between Biochemistry, Molecular Biology And Genetics?

Posted on by

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.

Stages Of Mitosis-An Important Study In Biology

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.

10 Amazing Facts About Plant Cells

Posted on by

Plants are necessary food for animals and human beings. Without plants, earth would have lost one of the main contributors of food for the living beings. Plants have cells which have many amazing facts.

PlantCellParts

  1. The first thing that is wonderful about plant cells is that they are the only producers of food by self on earth.
  2. Next they have amazing features like chloroplasts, rigid cell wall and vacuole. Their features resemble those of animal cells.
  3. Plants retain a definite shape due to the rigid cell wall. They take in lots of water but the rigid cell wall helps them retain their shape.
  4. The vacuole is the storage place for the waste of plant cell.
  5. Chloroplasts help plants manufacture food through photosynthesis.
  6. Without sun, plants are not able to produce food. With energy derived from sun, plant cell converts carbon- di- oxide and water into carbohydrates and sugar and prepare food.
  7. One   sixth of the energy derived from sun is used by plants and remaining energy goes to human beings and animals in the form of sugar and carbohydrates and forms their food.
  8. Without plant cells and their features, food for plants is impossible.
  9. Plants need sunlight to maintain the growth of plant cells.
  10. Plant cell features like nucleus, membrane and mitochondria are similar to animal cells.

Many plants are very small but they have mini organs which are used for producing food. Without plant kingdom, man might have suffered a heavy loss in food production.

Many such interesting topics are available in Biology. When students go to higher levels of learning, they would find the topics intricate and challenging. Online college Biology tutors are the right source for them to understand the topics in depth and the connecting links between them.

Online tutoring for Biology is the personalized help offered in one on one session that suits student needs at their best.

Balancing Eco System Through Food Webs Like Pond Food Chain

Posted on by

Ecology is an important branch of Biology explaining the various aspects of eco system in the context of the survival of different living organisms and their impact on one another. Food chain or food web is a process in Ecology that explains the sequence of energy consumed by living beings through a chain of production and consumption.

Food chain is an essential aspect of survival on earth. Be it animal, man or a plant, depending upon one another for food is a very common environmental factor. Biologists make many interesting facts about food chains and make us understand how such factors are imperative for balancing the eco system.

Food chain

Without energy, living on earth is impossible and you need to derive energy for your life through one or the other food resource. Plants derive energy from sun and prepare their food. They are eaten by rabbits like small animals which are killed by big animals for their food which in turn are hunted by predators as their prey. So passing of energy among the living organisms is through a food chain and it happens to all terrestrial and aquatic creatures.

Pond food chain

Pond food chain is about the beings in the pond which extract energy through various food resources. The beings in the pond form a food chain to draw energy and survive. For example, it starts with algae like plants deriving energy from sun for preparing their food. Plant is eaten by snails in the pond. Fish roaming about in the pond eats both snail and plant and get energy out of it. Fish is eaten by birds and the chain goes on.

Algae, water lily, Elodea, cattails are some of the plants in pond starting the food chain from there. They provide food for small insects like midge larva, tadpole and wood peck. These insects and fish provide food for birds like tree swallow, great blue herron, and red wing black bird and so on.

food chain

Food chain is an important component in eco system to balance the survival of living organisms. Producers, consumers, abiotic components and decomposers are the natural agents for systematizing eco system and for transmitting energy from one living being to the other. Forest food webs and aquatic ones like pond food chains are invariably part of eco system.

Doing Biology is great work and topics like Ecology are interesting for the scope they offer for exploring environmental factors, their importance and relevance in the biological aspects of the earth and water. Students find them awesome if they have proper training and exposure in these topics. That too, college level courses in biology are daunting for the fact they involve and complex thinking and pretty good diagrams.

Online tutoring services help students learn even the intricate topics in biology with ease and get ahead with their projects or tests without struggle. Online college biology tutors help students do their projects and lab work with ease through their tips and smart strategies. They provide easy to catch methods to understand intricate topics and help students review their old concepts through their personalized classes.
