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 endomembrane system is a series of compartments that work together to package, label, and ship proteins and molecules. in your cells, the endomembrane system is made up of both the endoplasmic reticulum and the golgi apparatus. these compartments are folds of membranes that form tubes and sacs in your cells.
