Question

During which phase of the cell cycle are chromosomes replicated?

a. s phase
b. m phase
c. cytokinesis
d. metaphase.

Answer 1

S phase of interphase... This is when the chromosomal DNA gets replicated.

Answer 2

DNA replication takes place only in the S phase of the cell cycle.

Step-by-step explanation:

In molecular biology, DNA replication is the organic means of creating two same duplicates of DNA from one original DNA molecule. This system happens in all existing organisms and is the foundation for biological inheritance.

The cells proceed to grow in G-1, S and G-2 phase. Although DNA replication takes place just in the S phase of the cell cycle.
