DNA Repair: Definition and Mechanisms | Genetics

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 [...]
