Question

multiple choice question
the region where sister chromatids are joined is called the

centurion.
centriole.
centromere.
center.

Explanation:

To solve this, we recall the definitions of each term:

• Centurion: A Roman military officer, not related to chromosomes.
• Centriole: A structure involved in cell division (forming spindle fibers), not the region joining sister chromatids.
• Centromere: The specific region on a chromosome where sister chromatids are joined.
• Center: A general term, not a specific chromosomal structure.

So the correct term is centromere.

Answer:

C. centromere
