Question

Select the correct statement with respect to mitosis.

• A. Chromatids start moving towards opposite poles in telophase
• B. Nuclear membrane and nucleolus are still visible at the end of prophase
• C. Chromosomes move to the spindle equator and get aligned along equatorial plate in metaphase
• D. Chromatids separate but remains in the centre of the cell in anaphase

Answer 1

The correct option is C Chromosomes move to the spindle equator and get aligned along equatorial plate in metaphase

During metaphase, each chromosome gets attached to two spindle fibres, one from each pole, in the region of its kinetochores. The kinetochore fibres contract and bring the chromosomes over the equator. where they align in the same plane.
Chromatids separate and start moving towards opposite poles in anaphase.
Nuclear membrane and nucleolus disappear at the end of prophase.
Thus, option c is the correct answer.
