why interphase called resting phase?
Interphase represents the phase during which a cell prepares itself for division, grows and DNA is replicated in it. Interphase occupies more than 95% of the duration of the cell cycle.
It is divided into 3 phases − G1, S and G2.
G1 (Gap1) phase is the phase between the end of mitosis and the initiation of DNA replication. The growth of the cell takes place in this phase.
S (synthesis) phase is the phase of DNA replication. DNA content doubles (from 2C to 4C), but chromosome number remains the same. (remains diploid; 2n only). In this phase, the centriole also duplicates.
G2 (Gap2) phase is the phase in which the proteins needed for mitosis are synthesised. Cell growth continues in this phase.
most of the cell division time is in interphase when the cell prepares for cell division but no actual division takes place
