Chapter 7, Problem 23MC
Summary Introduction
Introduction:
The generation of DNA off springs from the parental DNA was termed as DNA replication. DNA replication was carried out with the help of enzymes. Several enzymes are involved in the replication, such as helicase, primase, DNA polymerase, ligase, telomerase, nuclease, and so on. Each one possesses a separate role in the whole DNA replication process.
