Chromatin eukaryotic or prokaryotic
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, … See more Chromatin undergoes various structural changes during a cell cycle.
