A cell in the G1 phase has $8$ picograms of DNA. What will be the DNA content of the cell at the end of the G2 phase and at the end of Telophase II, respectively?

Solution

1. In G1, the DNA content is $8$ pg.
2. During the S phase, DNA replication occurs, doubling the content to $16$ pg by the end of G2.
3. Meiosis I reduces the DNA content by half, resulting in $8$ pg per daughter cell.
4. Meiosis II further reduces the DNA content by half, resulting in $4$ pg per daughter cell at the end of Telophase II.
5. Hence the answer is (A).
