Question

Describe the events taking place during interphase.

Answer 1

Interphase involves a series of changes that prepare a cell for division. It is the period during which the cell experiences growth and DNA replication in an orderly manner. Interphase is divided into three phases.
(i) G₁ phase 
(ii) S phase 
(iii) G₂ phase 

G₁phase - It is the stage during which the cell grows and prepares its DNA for replication. In this phase, the cell is metabolically active.
S phase - It is the stage during which DNA synthesis occurs. In this phase, the amount of DNA (per cell) doubles, but the chromosome number remains the same.
G₂phase - In this phase, the cell continues to grow and prepares itself for division. The proteins and RNA required for mitosis are synthesized during this stage.
