Exact replica of chromosome refers to ___________?
Correct answer: A. Chromatid
- A. Chromatid
- B. Centromere
- C. Kinetochore
- D. Arms
Explanation
After DNA replication, each identical copy of a chromosome is called a sister chromatid, and the two chromatids remain joined at the centromere. Students may choose the arms because they are visible chromosome regions, but arms are only parts of a chromatid and are not complete replicas.
