4. It is composed of nucleosomes.
5. During eukaryotic cell division, chromatin condenses to generate chromosomes.
6. Chromatin exists in two forms - Euchromatin and Heterochromatin.
7. Euchromatin refers to portions of chromatin that are loosely packed in a nucleus. Euchromatin is transcriptionally active.
8. Heterochromatin is the chromatin that is more densely packed and transcriptionally inactive.
