In this article we will discuss about the fidelity of the replication of DNA. The DNA being the carrier of genetic information it is essential that this information remains correct. But the DNA can be damaged by the action of chemical or physical agents. The cell therefore possesses repair systems which can maintain the integrity […]

The replication of the DNA can be schematically divided in three steps: initiation, elongation and termination. Step # 1. The Initiation Step: As seen above, no DNA polymerase can perform any de novo synthesis (contrary to RNA polymerases which can initiate by placing a complementary ribonucleoside-5′-triphosphate opposite to the DNA to be transcribed). The primer […]
