A group of cells is assayed for DNA content immediately before beginning mitosis and is found to have an average of 16 picograms of DNA per nucleus.How many picograms of DNA would be found in a cell nucleus following completion of mitosis and cytokinesis?
A)4
B)8
C)16
D)32

Question

Quizplus · Accepted Answer

Following mitosis and cytokinesis, each daughter cell will have the same amount of DNA as the parent cell had before mitosis, which is 16 picograms. Therefore, each nucleus will contain 8 picograms of DNA, as the original 16 picograms are divided equally between the two daughter cells.
