Pairs of identical chromatids are attached to each other at
an area called the
• A. centriole
• B. centromere
• C. Spindle
• D. chromosome

B. centromere

Explanation:

Identical chromatids are attached to each other at the centromere.

Other incorrect answers:

A. centriole

The centriole is an organelle that produces the mitotic spindle, also called spindle fibres.

C. spindle

Also called mitotic spindle or spindle fibres, they are produced by the centrioles. The spindle is like long, thin tentacles that attach to the centromeres and move the chromosomes within the cell. During metaphase, they move chromosomes to the equator or metaphase plate. During anaphase, they pull chromosomes apart.

D. chromosome

Chromosomes are condensed DNA. It is the entire structure which includes a centromere. The number of chromosomes in a cell is counted by the number of centromeres.
