Deoxyribonucleic acid (DNA) is synthesized during which phase of cell cycle in animal cells?

Phases of Cell Cycle
NEET
1

G₁ phase

2

S phase

3

G₂ phase

4

M phase

Solution:

DNA synthesis, also known as replication, takes place during the S phase (Synthesis phase) of the cell cycle. This process ensures that each daughter cell receives a complete set of chromosomes after cell division. G₁ phase is the period before DNA synthesis, G₂ phase is the period after DNA synthesis and before mitosis, and M phase is the phase of mitosis or meiosis.
