Q. An egg cell has 5pico gram of DNA in its nucleus. How much amount of DNA will be, in this animal, at the end of $G_{2}$-phase of mitosis?
A) 2.5pico gram
B) 5pico gram
C) 5 g
D) 20pico gram
Explanation
Egg is haploid and has 5 pg (pico gram) DNA. Its animal, which is diploid will be having 10 pg DNA. In S-phase, DNA doubles and therefore, in $G_{2}$amount of DNA will be 20 pg.
