DNA Replication Assignment

Answers

In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.[1] DNA replication occurs in all living organisms acting as the most essential part for biological inheritance. This is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.[2] The cell possesses the distinctive property of division, which makes replication of DNA essential.
