Based on the 'Data from the Experiment' table, what happens to the average amount of DNA per cell between 1.0 and 5.0 hours after the induction of meiosis?

  • A: It decreases by half.
  • B: It remains constant.
  • C: It approximately doubles.
  • D: It fluctuates randomly.

Explanation

At 1.0 hour, the average DNA amount is 24.0 fg. It increases steadily until it reaches a peak of 48.0 fg at 5.0 hours. This doubling of DNA content corresponds to the S phase DNA synthesis of the cell cycle, which precedes meiosis.
