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
- A10 pg
- B5pg
- C20 pg
- 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.
