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 identical copies of each chromosome are known as sister chromatids, and they are tightly associated together through G2 phase and early mitosis.

Detailed explanation-3: -Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the centromere. During cell division, they are separated from each other, and each daughter cell receives one copy of the chromosome.

Detailed explanation-4: -These identical copies are known as sister chromatids. These sister chromatids are held together by the centromere. G2 Phase: During G2, the cell makes proteins that are used in cell division.
