During metaphase, how many sister chromatids are present in a cell where 2n=4?N (A) 16
Answers
Ans . (C) 8
In this cell (2n = 4), there are 4 chromosomes present during metaphase ,but 8 chromatids.
Because each chromosome contains two chromatids during metaphase.
Metaphase is a stage of mitosis in the eukaryotic cellcycle in which chromosomes are at their second most condensed and coiled stage. These chromosomes align in the equator of the cell before being separated into each of two daughter chromatids.
The sister chromatids are not separated during metaphase. Metaphase leads to anaphase , during which each chromosome'sister chromatids separate and move to opposite poles.
