Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What structure holds the chromosome together in the center?
A
chromatin
B
chromatid
C
centromere
D
spindle fibers
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Centromere The centromere appears as a constricted region of a chromosome and plays a key role in helping the cell divide up its DNA during division (mitosis and meiosis). Specifically, it is the region where the cell’s spindle fibers attach.

Detailed explanation-3: -The centromere is the point at which two chromatids of a chromosome are held together.
