Question

If an haploid cell of an animal cell contain 'C' concentration of DNA than what is the amount of DNA in $G_2$ phase of Diploid cell

• A. 4C
• B. 2C
• C. C
• D. 8C

Answer 1

The correct option is A 4C

By late G2 phase the cell (diploid 2C) has already copied it's DNA because during S phase ( occurs before G2 ) the diploid cell doubles the total DNA by replication and hence the DNA is twice the total amount in diploid cell. Hence , if a haploid cell of same organism contains DNA equivalent to C , then the diploid cell in G2 phase will contain DNA equivalent to 4C.

So, the correct option is '4C'
