Question

In somatic cell cycle

• A. A short interphase is followed by a long mitotic phase
• B. DNA replication takes place in S phase
• C. In G${}_1$phase, DNA content is double the amount of DNA present in the original cell
• D. None of these

Answer 1

The correct option is B DNA replication takes place in S phase

The interphase of a typical cell cycle comprises of G${}_1$ phase, S phase and G${}_2$ phase. The S phase stands for synthesis phase in which DNA replication occurs followed by synthesis of histones.

So, the correct answer is option B.
