Answer:
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.
Step-by-step explanation:
DNA replication is the process by which DNA makes a copy of itself during cell division. DNA replicates in the S phase of the cell cycle and initiates at specific regions in the DNA sequence known as DNA replication 'origins'. Each molecule consists of a strand from the original molecule and a newly formed strand.
