Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Chromosomes are made up of two ____ which are held together by a ____

A	Chromatids ; Chromosome
B	Chromatids ; Centromere
C	Chromosomes ; Chromatids
D	Centromeres ; Chromatin

Explanation:

Detailed explanation-1: -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-2: -The centromere is the point at which two chromatids of a chromosome are held together.

Detailed explanation-3: -A sister chromatid is either one of the two chromatids of the same chromosome joined together by a common centromere. A pair of sister chromatids is called a dyad.

Detailed explanation-4: -Chromosomes and cell division After DNA replication, each chromosome now consists of two physically attached sister chromatids. After chromosome condensation, the chromosomes condense to form compact structures (still made up of two chromatids).
