Need a bit of homework help!

Post by LabRat010 » Sun Nov 01, 2009 6:27 pm

A cell containing 92 chromatids at metaphase of mitosis would, at its completion, produce two nuclei containing how many chromosomes?
A. 12
B. 16
C. 46
D. 23
E. 92
My reasoning: I picked 92 because mitosis produces two identical daughter cells. If there were 92 chromatids initially, shouldn't there be 92 chromatids (and 46 pairs) in the end?

At metaphase is the genome doubled, not so after the mitosis ;)

Cis or trans? That's what matters.

i didn't look at the link
but
here is your answer
92 chromatids will split into 4 cells with 23 chromatids
after this 2 will fuse. giving 46 chromatids. and then DNA duplication would produce 92 chromatids


your answer would be 46 chromosomes.
as the earlier 2 posts claimed
it isn't what you do that matters but it is how you do it
