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 (pg) per nucleus.
During the entirety of which stage of the cell cycle did the nucleus contain 6 pg of DNA?

a) interphase(G2)
b) prophase
c) interphase(S)
d) interphase(G1)

a) interphase(G2)

Explanation:

The nucleus would contain 6 pg of DNA at the interphase (G2) phase of the cell cycle.

The cell cycle is characterized by tow main phases, namely;

The interphase is divided into G0, G1, S, and G2 phase respectively while the m phase is divided into prophase, metaphase, anaphase and telophase respectively.

At the S phase of the interphase specifically, DNA is replicated and the amount of DNA in the cell becomes double.

Hence, a cell whose DNA amount ranges from 3 - 6 pg will have exactly 6 pg after the S phase of the interphase, which is G2 phase.

The correct option id a.

the correct answer is phenotype

there’s no image attached but i can if you want: )
