The given diagram shows mitotic cell division in a potato cell. The number of DNA molecules in the nucleus of the parent and daughter cells is:
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Parent cell has 48 chromosomes and number of chromosomes don't change in mitosis. So daughter cell will also have 48 chromosomes. So option B is correct. All other options either give incorrect chromosome number in parent cell or daughter cell. So A, C and D are incorrect.
