The fruit fly has 8 chromosomes (2n) in each cell. During interphase of Mitosis if the number of chromosomes at G
1
phase is 8, what would be the number of chromosomes after S phase?
- A4
- B32
- C8
- D16
Solution & Step-by-step Explanation
During the S-phase, the amount of DNA doubles (2C to 4C), but the number of chromosomes remains the same. If a cell has 8 chromosomes in G
1
, it will still have 8 chromosomes in G
2
, although each chromosome will now consist of two sister chromatids.
