Question
The amount of DNA in G1 phase of cell cycle is
Correct Answer
Option B is the correct answer.
Detailed Explanation
During the G1 phase, the cell has a diploid (2n) amount of DNA, representing the unreplicated genome. During the S phase, DNA replication occurs, resulting in the G2 phase having twice the amount of DNA (4n). Therefore, the DNA amount in G1 is exactly half of that found in G2.
Hint
Consider when DNA replication occurs during the cell cycle.
