Question

What will be the content of DNA in a somatic cell at G${}_2$ if its meiotic products have 20 picogram of DNA?

• A. 40 pg
• B. 20 pg
• C. 80 pg
• D. 160 pg

Answer 1

Answer: (C)

80 pg

Meiotic products of the somatic cell have 20 picograms of DNA it means haploid cell content is 20 picograms.

Thus the somatic cell is diploid in nature so it will contain 40 picograms of DNA. G2 phase of cell cycle comes after the S phase so in the S phase the amount of DNA gets doubles(because of DNA replication).

Thus the somatic cell will contains 40X2=80 picogram of DNA.
