Select the correct option: Synthesis of histone proteins occurs in

A$$G_1$$ phase
BInterphase
Correct Answer
CAnaphase
D$$G_0$$ phase

Solution

The cell cycle is a sequence of event which occurs during cell growth and cell division. It has two phases; interphase and the M phase. Interphase is the period between the end of 1 division and the beginning of next cell division. It is also known as resting phase or the non-dividing stage.
It has three phases G₁ phase which is the post-mitotic phase, the synthetic phase which is the S phase and the G₂ phase. During the S phase, DNA replication takes place and the amount becomes double. Here the synthesis of histone protein and non-histone chromosomal proteins also takes place.
So, the correct option is 'Interphase'
