A chromatid (Greek khrōmat- 'color' + -id) is one copy of a newly copied
chromosome which is still joined to the other copy by a single centromere. Before
replication, one chromosome is...
The two halves of a chromosome are called chromatids, or, more fully, sister-
chromatids. Each sister-chromatid contains one molecule of DNA.
