Question

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

• A. i).➡ a., ii).➡ b., iii).➡ c., iv). ➡ d.
• B. i).➡ d., ii).➡ c., iii).➡ b., iv). ➡ a.
• C. i).➡ c., ii).➡ d., iii).➡ a., iv). ➡ b.
• D. i).➡ b., ii).➡ a., iii).➡ d., iv). ➡ c.

Answer 1

The correct option is B

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.
