chromatids
Joined sister strands
Chromatids are the two identical strands of a replicated chromosome, joined at the centromere.
Before a cell divides, each chromosome copies itself, producing sister chromatids that will separate into daughter cells.
The chromatids pulled apart during cell division.
The term appears mainly in biology contexts discussing cell replication and genetics.
