Question

question 7 of 10
when is dna replicated in a cell?
a. during the g phases
b. during s phase
c. during interphase
d. during mitosis

Explanation:

Cell cycle has interphase (G₁, S, G₂) and mitosis. DNA replication occurs in S (synthesis) phase. G phases (G₁ - cell growth, G₂ - preparation for mitosis) don't involve DNA replication. Interphase includes S but also G₁ and G₂. Mitosis is for cell division (not DNA replication). So, DNA is replicated during S phase.

Answer:

B. During S phase
