Solution

Centromere is needed for the movement of chromosmes to poles .It is at the centromere ,the spindle fibres attach to chromosomes. Spindle fibres pull the daughter chromosmes topoles.
So Option 4 is right answer.

Q. Assertion :During anaphase, centromere of each chromosome splits to the chromatids separate. Reason: During anaphase, chromatids move to opposite poles.

Q. Identify the incorrect match

	Metaphase	Anaphase	Anaphase-1
1)	Chromosomes are moved to spindle equator	Daughter chromatids separate	Chromatids remain associated
2)	Chromosomes are moved to spindle equator	Centromeres are towards poles	Centromeres are towards the equator
3)	Starts with complete nuclear member disintegration	Centromeres are towards poles	Segregation of homologous chromosomes
4)	Starts with complete nuclear member disintegration	Centromeres split	Segregation of homologous chromosomes
