Detailed explanation-1: -The measured DNA levels ranged from 3 to 6 picogram per nucleus. In which state of the cell cycle did the nucleus contain 6 picogram of DNA, firstly observed. Correct answer is option ‘C’.
Detailed explanation-2: -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.
Detailed explanation-3: -According to the ploidy class distribution, the amount of DNA per diploid nucleus could be calculated. It corresponds to 7.8-8.2 X 10-12 g, in full agreement with the microinterferometric measurements (Table IV) .
Detailed explanation-4: -The measured DNA levels ranged from 3 to 6 picograms (pg) per nucleus.
Detailed explanation-5: -You know that 2n = 2 in this organism, that all the chromosomes are metacentric, and that each G1 cell nucleus contains 8 picograms of DNA.
