What happens to the chromosome number of a cell after the completion of the S phase if the initial number was 2n?
Show answer and explanation
Correct answer: It remains 2n
While the DNA amount doubles during the S phase, the chromosome number remains the same. If the cell had 2n chromosomes at G1, it will still have 2n chromosomes at the end of S phase.
