Question

What is the expected percent change in the DNA content of a typical eukaryotic cell as it progresses through the cell cycle from he start of the G1 phase to the G2 phase?

Answer 1

Answer:

+100%

Explanation:

The S phase of the cell cycle comes between the G1 and G2 phases. During the S phase of the cell cycle, the DNA of the cell is replicated. The process of DNA replication doubles the amount of the DNA present in the cell by the end of the S phase. Then the cell enters the G2 phase. Therefore, the G2 cell has double the DNA content as that of the G1 cell. If a G1 cell has 2C DNA, then the same cell in the G2 phase would have 4C DNA due to the replication in the S phase.
