What is chromatin?

Explanation:
Chromatin is the complex inside the cell nucleus formed by DNA tightly wrapped around histone proteins. This packaging with histones allows long DNA molecules to fit inside the nucleus and also helps regulate which genes are accessible for transcription. During cell division, chromatin condenses further to form chromosomes, and it relaxes to a more open form when genes need to be expressed. It’s not the cytoskeleton, not a skin layer, and not the energy-producing organelle.
