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 interplase (G1-S-G2), while it spends only one hour
in the M phase?
a)
Interphase follows mitosis, when daughter cells double their chromosomes,
which takes 23 hours.
b)
Interphase takes a long time because it is a preparatory stage where the cell
makes proteins and organelles and doubles its chromosomes.
Interphase consists of the Gap 1 and Gap 2 phases, in which the cell is
dormant while the chromosomes align.
d)
Interphase is when cells are dormant while they decide whether they want to
replicate their chromosomes.
