The nucleus of a gamete of an animal has 5 pg DNA. What will be the content of DNA in the somatic cell of the same animal at the end on G2 phase?

Options

  1. A10 pg
  2. B5pg
  3. C20 pg
  4. D40 pg

Correct answer

C. 20 pg

Step-by-step solution

Egg is a gametic cell having half the genetic content that is 5pg DNA (haploid). Thus, the diploid state of cell will have 10pg DNA. During the interphase, G2 phase occurs after the S phase (DNA duplication). The genetic content of cell in G2 phase will be double of the diploid state - 20pg.
