Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In its condensed form, the duplicated chromosome has a narrow ‘waist’ at a specialized region called the ____ where the two sister chromatids are most closely attached
A
centrioles
B
cytokinesis
C
centromere
Explanation: 

Detailed explanation-1: -In its condensed form, the duplicated chromosome has narrow “waist” at a specialized region called the centromere where the two chromatids are most closely attached.

Detailed explanation-2: -A chromatid is one of the two identical halves of a chromosome that has been replicated in preparation for cell division. The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere.

Detailed explanation-3: –The chromosome has a narrow “waist” at a specialized region called the centromere, where sister chromatids are attached.

Detailed explanation-4: -After DNA is replicated each chromosome consists of paired sister chromatids held together by cohesin.

Detailed explanation-5: -each sister chromatid has a centromere, a region containing specific DNA sequences where the chromatid is attached most closely to its sister chromatid.
