Question
In a chromosome, which structural feature is attached with two sister chromatids?
- Pellicle
- Chromomere
- Centromere
- Telomere
Hint:
Centromere
The correct answer is: Centromere
The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere. During cell division, spindle fibers attach to the centromere and pull each of the sister chromatids to opposite sides of the cell.
