In a diploid cell with 5 chromosome pairs (2n = 10), how many sister chromatids will be found in a nucleus at prophase of mitosis?
A) 5
B) 10
C) 20
D) 40

Question

Quizplus · Accepted Answer

At prophase of mitosis, the chromosomes have replicated and consist of two identical sister chromatids each. Therefore, the total number of chromatids in the nucleus is calculated by multiplying the number of chromosome pairs by 2 (number of chromatids per chromosome pair). Thus, in this diploid cell with 5 chromosome pairs, there are a total of 10 sister chromatids (5 pairs x 2 chromatids per pair = 10 chromatids).
