Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens during the S phase of Interphase?
A
Cells divide
B
Cells grow and make protein
C
Cells copy their DNA
D
Cells Die
Explanation: 

Detailed explanation-1: -During the S phase, DNA is duplicated into two sister chromatids, and centrosomes, which give rise to the mitotic spindle, are also replicated. In the G2 phase, energy is replenished, new proteins are synthesized, the cytoskeleton is dismantled, and additional growth occurs.

Detailed explanation-2: -S phase is the period during which DNA replication occurs.

Detailed explanation-3: -DNA synthesis begins in S phase as the replicative helicase unwinds and separates the two strands of the DNA double helix [7]. As the helicase unwinds DNA, DNA polymerase synthesizes DNA utilizing the exposed single stranded DNA as a template.
