chromatid
Duplicated chromosome copy
A chromatid is one of the two identical strands of a duplicated chromosome, joined at the centromere.
Before cell division, each chromosome replicates to form two sister chromatids; during division, these separate so each daughter cell receives one copy.
The chromatids pulled apart during anaphase.
