The dictionary of coded language of genetic information is called cryptogram. The simplest and smallest possible code is a single code or singlet code which specifies that one amino acid is synthesized by one nucleotide. Singlet code is not possible for coding 20 different amino acids. Then how many letters would be used as a code for a single amino [...]
In this article we will discuss about the definition and mechanisms of DNA repair. Definition of DNA Repair: One of the main objectives of biological system is to maintain base sequences of DNA from one generation to the other. Changes in DNA sequence arise during replication of DNA damage by chemical mutagens and radiation. During replication if incorrect nucleotides have [...]
In this article we will discuss about:- 1. Definition of Recombinant DNA 2. History of Recombinant DNA 3. Milestones. Definition of Recombinant DNA: For centuries humans have been altering the genetic makeup of organisms by selective breeding of plant and animals. The deliberate modification in genetic material of an organism by changing the nucleic acid directly is called genetic engineering [...]
