4 Chromatin, Chromatids, and Chromosomes Before cell division Chromatin is a mixture of DNA and protein in the nucleus. The DNA is copied (replicated) During Cell Division The chromatin coils up into chromosomes.

5 Each chromosome has two chromatids – The chromatids are held together by a centromere – Each chromatid contains identical DNA – The chromatids will split apart and end up in different cells – When the chromatids split, each chromatid will be considered a chromosome Chromatin, Chromatids, and Chromosomes
