Question

In anaphase of mitosis:

(a) Chromosomes move to spindle equator and get aligned along metaphase plate.

(b) Centromere of each chromosome is towards the equator when chromosomes move away from the equatorial plate.

(c) Each chromosome arranged at the metaphase plate is split simultaneously.

• A. a and b are incorrect and c is correct
• B. b and c are incorrect and a is correct
• C. a and c are incorrect and b is correct
• D. a, b and c are correct

Answer 1

The correct option is A a and b are incorrect and c is correct

At the onset of anaphase, each chromosome arranged at the metaphase plate is split simultaneously and the two daughter chromatids, now referred to as chromosomes of the future daughter nuclei, begin their migration towards the two opposite poles.

Chromosomes move to spindle equator and get aligned along metaphase plate through spindle fibres to both poles during metaphase.
As each chromosome moves away from the equatorial plate, the centromere of each chromosome remains directed towards the pole.
