A cell has 30 chromosomes in G2 phase (sub-phase of interphase) of the cell cycle. What would be the total number of sister chromatids in prophase-I of the same cell?
Correct answer: C. 60
- A. 15
- B. 30
- C. 60
- D. 90
Explanation
Number of chromosomes in G₂ = 30Each chromosome = 2 sister chromatidsSo, total sister chromatids =30 × 2 = 60.So, C is the correct option.
