DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
Replicating DNA. The dsDNA strand is unzipped by helicase and DNA synthesis occurs at the Y-shaped replication fork in the five prime (5â) to three prime (3â) direction. DNA has a direction because it is an asymmetrical molecule and the direction of the strand is determined by the orientation of the deoxyribose sugar.
