Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication. During mitosis and WebFinal answer. Step 1/4. There are 2 types of chromatin:-. 1. EUCHROMATIN: chromatin that is loosely packed and is stained light . 2. HETEROCHROMATIN:- chromatin that is tightly packed and stains dark.
