Biotechnology: Principle & Processes Test 4

DNA fingerprinting is a chemical test that shows the genetic makeup of a person or other living things. It’s used as evidence in courts, to identify bodies, track down blood relatives, and to look for cures for disease.DNA fingerprinting in the identification of paternity since it is very remote possibility to have two individuals have the same repeats of satellite DNA throughout the genome except they share a biological relationship. This is because a child gets half DNA from father and half from the mother.

Fermentation is defined more from the point of view of engineers. They see fermentation as the cultivation of high amount of microorganisms and biotransformation being carried out in special vessels called fermenter or bioreactors.

The polymerase chain reaction is a technique that is used for in vitro replication of specific DNA sequence using thermostable DNA polymerase.
Polymerase chain reaction (PCR)  is a technique by which DNA can be cloned or amplified in vitro by a thermostable enzyme DNA Taq Polymerase. PCR has three steps: Denaturation, Annealing and Extension.

Cellular totipotency is the ability of a plant cell to give rise to an entirely new plant is called cellular totipotency. Explant is grown in culture medium at appropriate temperature and aeration. This method of producing thousands of plants through tissue culture is called micropropagation.

The human insulin is a small globular protein that consists of 51 amino acid residues in two polypeptide chains, chain A (21 residues) and B (31 residues), which are linked by two disulfide bonds in addition to one disulfide loop in chain A.
