Question

Mitotic anaphase differs from metaphase in possessing

Options

A.same number of chromosomes and same number of chromatids
B.half number of chromosomes and half number of chromatids
C.half number of chromosomes and same number of chromatids
D.same number of chromosomes and half number of chromatids

Solution

Mitotic metaphase is the best stage to observe the structure, size and number of chromosomes in a cell . Centromeres of all chromosomes lie closely at equator and their arms in different directions towards poles. Chromosomes are short in metaphase but thickest in anaphase . In anaphase , centromere of each chromosome divides so that each sister chromatid now has its own centromere. Thus , mitotic anaphase differes from metaphase in possessing same number of chromosomes and half number of chromatids .
