* DNA polymerase • DNA polymerase is an enzyme that synthesizes the double-stranded DNA molecule . • Molecular weight of DNA polymerase is 400 k Dalton . • DNA polymerase's mechanism is during DNA replication where by it synthesizes new DNA s…
Inflammation is fundamentally, a protective response of the body against any offending agent or tissue damage. It involves responses of the vascular tissues and leukocytes which help in getting rid of the primary cause of insult and necrotic cells …
Particie bombardment or biolistic or gene gun is the most important and effective diret gene transfer method in regular use. In general it is a way of transfecting cells. Suppose you want to deliver a gene or plasmid into the diffrent cell and this pa…
Microbes and dead cells could trigger inflammatory mediators to cause inflammation, which is basically the body’s response of delivering leukocytes and plasma proteins to the site of infection or injury, so that the offending agents could be remov…
During nucleotides polymerization two strands of DNA come together to form a long double helix, with millions of base pairs. But to go from this to a more complete understanding of all the chromosomes in every one of your cells is a pretty big lea…
Gel electrophoresis is a method of separating large molecules like segments of DNA. When we introduced some concepts in biotechnology, for make recombinant DNA plasmids and insert them in bacteria to produce many copies of a gene, or many copies of…
Anthrax is a disease that is most recently famous for being sent through the mail as a biological weapon. Anthrax is an ancient disease, and many researchers believe we can trace it all the way back to the year 700 BC in ancient Egypt. Over the …
The linear sequence of bases in DNA constitutes alphabet (hereditary lettering of 4 bases - A, T, G, C ) which 'codes' for another linear structure, a protein, written in another alphabet of 20 amino acids. All properties of protein, includi…
The immune system protects the human body against disease by dispatching a bunch of immune cells, whenever the body encounters foreign material or antigens . These immune cells or effector cells elicit an inflammatory response in order to remove or …
Carbon cycle is the process of degradation of complex organic compounds and fixation of carbon dioxide. Carbon is the most Important element in the structure of a cell. 40-50% of a cells dry-weight is carbon. This carbon comes from CO2, or organic ca…
Enzymes cause biochemical transformations within the cell. by following rules of chemical kinetics. A number of factors are known to interfere with activity of enzymes. They are as under: Concentration of substrate Concentration of Enzyme Temperatu…
