Question

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.

Answer 1

Answer: a. During DNA replication, enzymes unwind DNA to provide a template for making identical DNA strands.

Explanation: The purpose of DNA replication is to produce genetically identical DNA molecules.

Replication is the process of copying a double-stranded DNA molecule into two identical daughter DNA. The enzyme known as helicase unwinds the DNA so that each strand will serve as a template for the synthesis of a complementary DNA strand. The. Two identical daughter DNA produced each contains one parent DNA strand and one new complementary strand.

Answer 2

The main purpose of DNA replication is - a. During DNA replication, enzymes unwind DNA to provide a template for making identical DNA strands.

DNA Replication

is the process by which DNA is replicated or a new copy of DNA is synthesized. It is catalyzed by the enzyme DNA-dependent DNA polymerase.

It uses the DNA strand as the template and synthesized a new strand of the daughter DNA based on the principle of complementary base pairing. It takes place in three steps; initiation, elongation, and termination.
