What substances is chromatin made of?

Answer 1

Chromatin is made of DNA wound around proteins called histones. Essentially, chromatin is tightly packaged DNA. If DNA is left as a strand inside the nucleus, it could get damaged or tangled, so the cell has an organized way of packaging DNA at times when the DNA does not need to be used. The way cells package DNA is by wrapping the DNA strands around circular proteins called histones.
