Biology Question! 10 pts will be awarded asap

-C) A single DNA molecule is presumably just a nucelotide, and clearly a chromosome is more than a single nucleotide.......
Helloooo!
Imagine a replicated chromosome taken from a cell during metaphase I of
meiosis. It consists of two chromatids joined by a centromere.

It would be incorrect to conclude:
A. The chromatids will end up in different daughter cells
B. Both chromatids are genetically identical
C. Each chromatid consists of a single DNA molecule
D. The centromere will break during Anaphase II of meiosis

Is it just me or are all of them correct??????

The only way the chromatids are different would be if crossing over has taken place
and if you think about it the centromere doesnt actually 'break' it just seperates
i have no idea which on it is...so yeah if you say which and explain you'll get the 10pts ASAP :D

Hi. Crossing over takes place in prophase I, which comes before metaphase I. Looks like B would be the incorrect conclusion here.
