A human cheek cell's cycle is 24 hours. The stages within the cell cycle vary in length. G1 phase - 11 hours, G2 phase - 4 hours
, S phase - 8 hours, M phase - 1 hour. Why does the cell spend 23 hours in interphase (G1-S-G2), while it spends only one hour in the M phase? a.Interphase consists of the Gap 1 and Gap 2 phases, in which the cell is dormant while the chromosomes align.
b.Interphase is when cells are dormant while they decide whether they want to replicate their chromosomes.
c.Interphase follows mitosis, when daughter cells double their chromosomes, which takes 23 hours.
d.Interphase takes a long time because it is a preparatory stage where the cell makes proteins and organelles and doubles its chromosomes.
The cell needs a lot of preparation and checks in G1, S and G2 to do mitosis. especially in the G1 phase which is the longest phase. It is explained by the fact that the cell should "rest and recover" after the last mitosis before getting into the second one
