A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 8 picograms of DNA per nucleus. How many picograms of DNA would be found in a nucleus at prophase of mitosis?
A) 4
B) 8
C) 16
D) 24

Question

Quizplus · Accepted Answer

During prophase of mitosis, the DNA content of a nucleus is doubled compared to immediately after mitosis because DNA replication occurs during the S phase of the cell cycle. Therefore, if a nucleus has 8 picograms of DNA immediately after mitosis, it would have 16 picograms at prophase.
