Match the following time spans with their actual phases in a eukaryotic cell cycle.
Column I Column II
i). 10 hr a. M Phase
ii). 9 hr b. G2 Phase
iii). 4 hr c. S Phase
iv). 1 hr d. G1 Phase
i).→ d., ii).→ c., iii).→ b., iv).→ a.
On an average, a human cell spends 24 hours of time to divide once, with the time span of phases as:
d. G1-phase - 10 hrs (i),
c. S-phase - 9 hrs (ii),
b. G2-phase - 4 hrs (iii) and
a. M-phase - 1hr (iv).
Therefore, the correct option is B. - i).→ d., ii).→ c., iii).→ b., iv). → a.
