Chromatid - Wikipedia
WEBA chromatid (Greek khrōmat-'color' + -id) is one half of a duplicated chromosome. Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids. [1]
Chromatid | Description, Characteristics, & Cell Division
WEBChromatid, one of a pair of daughter strands of a replicated chromosome. Chromatids serve an essential role in cell division, ensuring the accurate division and distribution of chromosomes to new daughter cells. Chromatids are formed during chromosome duplication, which occurs prior to cell

WEBApr 24, 2024 · 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. During cell division, spindle fibers attach to the centromere and pull each of the sister chromatids to opposite ...
