Q. An egg cell has 5 pico gram of DNA in its nucleus. How much amount of DNA will be in this animal at the end of $G_{2}$ phase mitosis?

Solution:

Egg is haploid and has $5\, pg$ (pico gram) DNA. Its animal which is diploid will be having $10\, pg$ DNA. In Sphase DNA doubles and therefore, in $G _{2}$ amount of DNA will be $20\, pg$.
