Within the chromosomes, each chromatid contains _ DNA molecule:
Correct answer: A. One
- A. One
- B. Two
- C. Three
- D. Half
Explanation
Even when a chromosome is replicated, it has two sister chromatids. Each sister chromatid has one DNA molecule. Overall, the chromosome has 2 DNA molecules in the replicated state but each chromatid still has only one DNA molecule.
