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?

a) g0 b) g1 c) g2 d) m

c) G2

Explanation:

A cell cycle is the chorological order of events that allow them to divide and produce new cells. The cell cycle consists of interphase and M (mitosis). Interphases includes gap1(G1), synthesis (S-phase)  and gap 2 (G2) phase.  

During S-phase or synthesis phase, the cell replicates or duplicates its DNA. Coping of DNA requires lots of energy because replication requires synthesis of lots of nucleotides. At the end of S-phase, the cell have two complete sets of genetic material.

During G2 phase cells both the copies of their DNA are correct and intact. Thus, as per question, during G2 phase it can be observed that the nucleus of a cell contain 6 picograms of DNA.
