Question

At what stage of cell cycle does DNA synthesis occur?​

Answer 1

Explanation:

S phase

In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

Answer 2

Explanation:

ANSWER

There are 4 phases of the cell cycle, namely G

1

phase, S phase, G

2

phase and M phase. During G

1

phase or gap 1 phase, the cell increases in size. Also, various proteins are synthesized in this phase. During S phase or synthesis phase, the DNA replication takes place. During G

2

phase, cell continues to grow until it enters the M phase or mitosis phase. Cell division takes place in M phase.

Thus, the correct answer is 'S phase.'
