DNA replication occurs in which phase of cell cycle?

a) Mitosis

b) Prophase

c) Interphase

d) Metaphase

e) Cytokinesis

The correct answer is: c) Interphase

Explanation:

DNA replication does not occur during mitosis or cytokinesis. Instead, it takes place in the S-phase (Synthesis phase) of Interphase, where the entire DNA content of the cell is duplicated. This ensures that when the cell divides, each daughter cell receives an identical set of genetic material.

So, replication = S-phase of Interphase.
