Question

Match the stages of mitosis with the events happening in them.
$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \left(a\right)\text{Prophase}& \left(i\right)\text{Chromosomes arranged on equatorial plate}\\ \left(b\right)\text{Metaphase}& \left(ii\right)\text{Formation of nuclear membrane}\\ \left(c\right)\text{Anaphase}& \left(iii\right)\text{Condensation of chromosomes}\\ \left(d\right)\text{Telophase}& \left(iv\right)\text{Spindle fibres pull chromatids}\end{array}$

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

Answer 1

The correct option is B a-iii, b-i, c-iv, d-ii

Mitosis is divided into the following stages:
1. Prophase: The nuclear membrane disappears and chromatin condenses to form chromosomes.
2. Metaphase: The condensed chromosomes are arranged in the equatorial plate of the cell.
3. Anaphase: Spindle fibres attach to the chromosomes and start pulling the chromatids apart towards the poles.
4. Telophase: The chromatids decondense and nuclear membrane starts to form around them.
