Question

Measurements of the amount of dna per nucleus were taken on a large number of cells from a growing fungus. The measured dna levels ranged from 3 to 6 picograms per nucleus. In which stage of the cell cycle did the nucleus contain 6 picograms of dna?

Answer 1

Answer:

It's on the G2 stage

Explanation:

During the cell cycle, DNA levels range from a minimum during G1 to a maximum after S phase but before cytokinesis. Since the cell in question has more than the minimum but equally to the maximum per nucleus, it must be in the final phase, which is G2.
