As a cell prepares to divide during the cell cycle, DNA replication must take place. During the S-phase, DNA strands unwind and replication occurs along the 2 separated strands. What is the main purpose of DNA replication?
a. During DNA replication, enzymes unwind DNA to provide a template for making identical DNA strands.
b. During DNA replication, enzymes are made which are important in maintaining homeostasis.
C. During DNA replication, copies of DNA are made so there is a continuous supply of DNA available for translation.
d. During DNA replication, a copy of RNA is made which is used as a code for protein synthesis.
