histone

histone
Noun
pl: histones

This term is used exclusively within the specialized register of molecular biology and genetics. It describes the specific proteins that act as spools around which DNA winds, facilitating the extreme compaction required to fit a long genome into a microscopic nucleus.

Because it refers to a specific class of biological molecules, it is used as a countable noun when referring to individual protein units or different types of histone proteins (e.g., H2A, H2B, H3, and H4).
