Q.

Select the incorrect statement with reference to mitosis :

  1. A

    All the chromosomes lie at the equator at metaphase.

  2. B

    Spindle fibres attach to centromere of chromosomes.

  3. C

    Chromosomes decondense at telophase.

  4. D

    Splitting of centromere occurs at anaphase.

Solution

Spindle microtubules do not attach directly to the centromere of chromosomes. They attach to the kinetochores, specialised protein complexes assembled on the centromere region.

Statement (2) is therefore imprecise and is treated as the incorrect statement. The other statements describe accurate features of mitosis.
