Verified step by step guidance

Understand that chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells.

Recognize that histone proteins are a key component of chromatin, playing a crucial role in its structure.

Learn that histones help package DNA by forming a structure known as a nucleosome, where DNA is wrapped around a core of histone proteins.

Acknowledge that this packaging allows the long DNA molecules to fit within the cell nucleus and also plays a role in regulating gene expression.

Conclude that the primary role of histone proteins in chromatin is to help package DNA into a compact, dense shape, facilitating efficient storage and regulation.
