Question

During interphase of the cell cycle, a growing cell undergoes DNA replication. What is the primary function of DNA Replication?

a. To create haploid sex cells to be used in reproduction
b. To edit the DNA code and correct mistakes
c. To add genetic variation through mutations and the process of crossing-over
d. To provide an exact copy of DNA to daughter cells once the cell divides

Answer 1

DNA replication's primary function is to ensure each daughter cell receives an identical copy of the parent cell's DNA upon division. This process occurs during the S phase of the cell cycle.

Step-by-step explanation:

The primary function of DNA replication during interphase is D. To provide an exact copy of DNA to daughter cells once the cell divides. This process ensures that, after mitosis or meiosis, each daughter cell inherits a complete and identical set of chromosomes. This replication occurs during the S phase of the cell cycle, setting the stage for the subsequent division into two new daughter cells with the same genetic material as the parent cell.
