3. Describe the events taking place during interphase.


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.
 G1 phase
 S phase
 G2 phase
G1 phase – 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.
G2 phase – 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.
