Select the incorrect statement with reference to mitosis:

Select the incorrect statement with reference to mitosis:
  1. Spindle fibres attach to centromere of chromosomes.
  2. Chromosomes decondense at telophase.
  3. Splitting of centromere occurs at anaphase.
  4. All the chromosomes lie at the equator at metaphase.

Solution

A kinetochore is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. Spindle fibres attach to the kinetochores which is a proteinaceous assembly formed over the centromere.
