Question

. Match the following.

i) Prophase ( ) A) Nuclear membrane form round daughter

nuclei

ii) Metaphase ( ) B) Centrosome split, separating chromatids

iii) Anaphase ( ) C) Chromosome split length wise to form

chromatids

iv) Telophase ( ) D) Chromosomes more to spindle equator​

Answer 1

The matched answers are:

1. Prophase: Chromosome split length wise to form chromatids

2. Metaphase: Chromosomes move to spindle equator.

3. Anaphase: Centromeres split separating the chromatids.

4. Telophase: Nuclear membrane form round daughter nuclei.

Detailed Discussion of the stages:

• Prophase: In this stage, nuclear condensation occurs. There is initiation of disappearance of nuclear membrane and other cell organelles.

• Metaphase: In this stage, the condensed chromosomes come to the equator position. It is the best stage to study the morphology of the chromosomes.

• Anaphase: In this stage, the centromere of the chromosome split and the sister chromatids undergo separation. The chromatids go towards separate poles of the cell.

• Telophase: In this stage, there is reappearance of two nuclear membrane, which forms the daughter nuclei. This stage is followed by cytokinesis.
