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 would the nucleus contain 6 picograms of DNA

The correct answer is G2  

Explanation:

The G2 phase is a short phase in the cell cycle between Synthesis (S) and Mitosis I (MI) stages, in which the DNA content is double than the DNA amount observed in the original cell. The G2 phase is used to repair DNA damages that occurred during DNA synthesis

the answer is c.) there is a warm front in region a and a stationary front in region b.

b is dominant over the allele for the white fur.
