Chromatid is _________ ?
Correct answer: A. One half of chromosome
- A. One half of chromosome
- B. Haploid chromosome
- C. Complete chromosome
- D. Duplicate chromosome
Explanation
After DNA replication, a chromosome consists of two identical sister chromatids joined at the centromere, so one chromatid forms one half of the duplicated chromosome. Students may choose “duplicate chromosome” because a chromatid contains a duplicate DNA molecule, but a chromatid is not the whole duplicated chromosome.
