Question

DNA and histone proteins are synthesized during which of the following phase of cell cycle?

• A. S phase
• B. G${}_2$ phase
• C. G${}_1$ phase
• D. None of these

Answer 1

The correct option is A S phase

S phase is the synthesis phase of cell cycle. It is characterised by a synthesis of histone proteins and replication of DNA of a chromosome. This protein helps in the formation of cellular structures like spindle fibre which further helps in cell division.

So, the correct answer is option A.
