Molecular biology is the branch of biology that deals with the molecular basis of biological activity. This field overlaps with the other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concern itself with understanding the interaction between the various system of the cell ,including the interactions between types of DNA, RNA and protein biosynthesis as well as learning how these interaction are regulated.
The study of physical, chemical and biological macromolecules is termed as Molecular Biology. Max Pertuz is known as the father of molecular biology. The basics of Molecular biology is the DNA which is being used for following application-
-Genetic engineering
-DNA profiling.

They perform a vast and different type of functions in living organisms, which also include important functions like catalyzing metabolic reactions, replicating DNA, responding to different stimuli, and also transportation of molecules from one location to another within a cell or from one cell to different cell. Proteins differ from one another basically in their amino acids sequence, which is generally dependent on the nucleotide sequence of their genes, and which in turns results in folding of the protein into a specific 3D structure that determines its functions.
A linear chain of amino acid is called a polypeptide and a protein contains generally more than one long polypeptide.
Why do we study proteins? The study of proteins and their function important for understanding basic concepts of cells and organisms. Proteins are important in biology as they are:
• are Biocatalysts that help in maintaining the metabolic processes that are happening in the cell,
• They form the structural elements that are found inside and outside of the

And at last Sodium acetate is added to remove RNA impurities. The pellet of DNA is obtained which is dissolved in TE buffer and from this buffer DNA can be isolated and also we can go for Agarose gel electrophoresis for Visualization of
Biological Researchers are key in the animal sector of agriculture. They are becoming more important as we have to provide for more people. This world has not reached its cap, therefore this world can not stop being resourceful. Biological researchers in agriculture play a big part in finding and keeping the genetics of certain production animals to keep the producing effective. Researchers have developed technology and the ways to take certain chromosomes and incorporate them into a genome sequence to obtain the genetic outcome that they want.
The Solid sequencing platform, produced by Technologies/Applied Biosystems (ABI), performs sequencing by ligation method. Similar like the Roche 454 library preparation, genomic double strand DNA were sheared into small pieces and ligated with two types of adatptors P1 and P2 on two ends. One end with P1 adaptor binds onto the surface of the magnetic bead and emulsion PCR takes place to amplify single nucleotide fragment. Then the oil was washed out and four fluorescent labeled di-bases probes were added into the beads mixture. By matching the 1st and 2nd position of the template by di-base probes, fluorescence was detected and the extra tail with fluorescent probe is cleaved out.
Introduction Chemical reactions are seen in many instances, including those in which one substance is being converted to another. Natural chemical reactions will occur without intervention, however they occur slowly. Enzymes become important in these situations. Enzymes are proteins that act in cells to ensure reactions occur at appropriate speeds. In other words, they act as catalysts.
To begin the process, a pre-prepared 1% agarose gel was obtained. The gel chamber was set up by placing the agarose gel into the chamber and submerging it in plentiful TAE buffer. The wells were filled with both PCR and DNA and shared between six students. The wells were labeled 1-7. The first well was pre-loaded with DNA ladder and labeled as 1 microliter kb DNA ladder.
Avery-MacLeod-McCarty: In the 40’s genes were classified as a separate element of heredity that generates a metabolic function controlled by enzymes. It was also thought that genes were proteins. Experiments by Oswald T. Avery in 1944 explained that nucleic acid and deoxyribose acid previously known as the organisms ubiquitous turned out to be the chemical basis for heritable changes in the bacteria. Oswald Avery was a immunochemist in a hospital named The Hospital of the Rockefeller institute, which was for medical research.
Nutrition is the process of providing or obtaining the food necessary for health, growth, metabolism, and repair. Food is separated into two groups of requirements; macronutrients and micronutrients. Macronutrients is defined by types of food that are highly required and a bigger amount of them in the diet. Examples of macronutrients would be: carbohydrates, proteins and fats.
Carbs and fats are needed in the diet for energy but proteins are not intended to be used as energy. What do they do for the body instead? List a few of the functions of proteins. Type your response here: Proteins do so much for the body. They help with your hair and nails.
In this step 109 of 10 kb cassettes were generated. All the cassettes that included errors were eliminated except for 19 polymorphic differences that were not important. Additional recombination provided 11 of 100 kb cassette assemblies. Since these assemblies were too large to be extracted from the E. coli, they were assembled in yeast. Exonuclease treatment and Ion Exchange Chromatography were some of the methods used to refine the DNA pulled out from the yeast.
1 “substrate” and another “ enzyme.” Instead of using the distilled water, this time you are going to use different pH buffer in the enzyme test tube. In the substrate tube, add 7 mL of distilled water, 0.3 mL of hydrogen peroxide, and 0.2 mL of guaiacol for a total volume of 7.5 mL. For the enzyme tube, instead of distilled water add the pH solution (3) and 1.5 mL of peroxidase which equals a total volume of 7.5 mL. Use the dH2O syringe for our pH solution. To clean the syringe, flush it by drawing 6 mL of distilled water.
Proteins are made up of peptide bonds holding amino acids together to perform biological functions like enzymes, antibodies, for transport and structure (Asmus, 2007). Lastly, nucleic acids
The roles are as follows for the bacterial cells, the structure flagella are the swimming movement of the cell, pili stabilizes the cells during DNA transfer, the capsules are used as protection for the cell when a method of killing or digestion is happening. The cell wall confers rigidity and the shape they have, the plasmic membranes are the barriers and the location for the enzyme systems which produces energy. The ribosomes like animal and plant is the factor for protein synthesis. The other functions like the Chromosomes and the plasmid make up the DNA of the cell. Explain how bacteria cells make energy for cellular processes.
DNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems.
For that reason, I believe it is important to learn about this upcoming breakthrough in the science and medical field. C. Speaker Credibility: As a Biology major I have learned about DNA and cells and taken my research to the next step by studying how genes work. I also conducted an interview with my biology lab teaching assistant to learn more about the process. D. Thesis: Learning about the promise of gene therapy is important because it could change the future of medicine forever, impacting our lives, our kids’ lives and so on. E. Preview of Main Points:
