How many chromatids are present in a diploid (2n) cell of 36 chromosomes throughout the prophase stage of mitosis?
The solution is as follows...
Chromosomes are replicated during the S phase of a cell cycle. In the case of a (2n = 36) diploid cell, 36 x 2 = 72 chromatids will appear observable when chromatin fibers begin to condense at prophase of mitosis.
However, I think as follows...
The question said 2n=36 in prophase, so S phase is already passed. And the replicated chromosome # is 36. One chromosome = 2 chromatid. They are asking the # of chromatid. That's why 36*2=72. I mean it's not because of replication but because of 1 chromosome = 2 chromatid
Anybody explain?
