Question

Match the following time spans with their actual phases in a eukaryotic cell cycle.

$\begin{array}{cc}\text{Table I}& \text{Table II}\\ \text{I) 10 hr}& \text{a. M Phase}\\ \text{II) 9 hr}& \text{b.}{G}_1\text{Phase}\\ \text{III) 4 hr}& \text{c. S Phase}\\ \text{IV) 1 hr}& \text{d.}{G}_2\text{Phase}\end{array}$

• 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:

G₁ Phase - 10 hr
S Phase - 9 hr
G₂ Phase - 4hr
M Phase - 1hr

Therefore, the correct option is B. - i).$\to$ b., ii).$\to$ c., iii).$\to$ d., iv). $\to$ a.
