Answer:
The interphase, though called the resting phase, is the time during which the cell is preparing for division by undergoing cell growth and DNA replication. The interphase is-divided into three further phases:
(i) G1-phase (Gap 1)
(ii) S-phase (Synthesis)
(iii) G2-phase (Gap 2)
G1-phase corresponds to the interval between mitosis and initiation of ONA replication. During G1-phase the cell is metabolically active and continuously grows but does not replicate its DNA. S or synthesis phase marks the period during, which DNA synthesis or replication takes place.
During this time, the amount of DNA per cell doubles.
During the G2-phase, proteins are synthesized in preparation for mitosis, while cell growth continues. Cells in this stage remain metabolically active but no longer proliferate unless called on to do so depending on the requirement of the organism.
