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?
Select one:

a.
Interphase is when cells are dormant while they decide whether they want to replicate their chromosomes.

b.
Interphase consists of the Gap 1 and Gap 2 phases, in which the cell is dormant while the chromosomes align.

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.
