Question

What would be the DNA content in a diploid cell at prophase-I, if its male gamete has $40$ pg DNA?

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

Answer 1

The correct option is D $160$ pg

D. 160 pg

Solution : The DNA content in a diploid cell would be double of the haploid male gamete. So the diploid cell just before meiosis during prophase I would have 160 pg because the diploid cell would have doubled its DNA before the M phase.

So the correct answer is " 160 pg".
