Question

Mention three significant changes that occur in a cell during interphase.

Answer 1

Interphase:

1. The G₁ phase, S phase and G₂ phase together form the interphase.
2. During the G₁ phase, the cell grows in size, besides synthesising RNA and proteins.
3. In the S phase, replication of DNA and synthesis of histone proteins occur.
4. In the G₂ phase, the synthesis of RNA and proteins continues and two centrosomes are formed by replication of a single centrosome.
