The nucleosome is the fundamental subunit of chromatin.en.wikipedia.org/wiki/NucleosomeA nucleosome is a structure consisting of DNA wound around histone proteins, somewhat resembling beads on a string. The nucleosome is a fundamental unit of chromatin, the substance within a chromosome.sciencenotes.org/nucleosome-structure-and-function/The double-stranded DNA helix associates with the core histones to form nucleosomes. These nucleosomes are further organized into a 30 nm fiber by the linker histone, H1. The fiber then associates with additional proteins to form loops and higher-order heterochromatin packing.bio.libretexts.org/Courses/Citrus_College/Citrus_C…Nucleosomes are the fundamental subunit of chromatin in the nucleus consisting of a segment of DNA wound around a core octamer of 8 histone proteins. In contrast, histones form the protein core of the nucleosome. There are five prominent families of such proteins (H1 to H5).www.sciencefacts.net/nucleosome.htmlWhile histones are proteins that form octamers and provide structural support to DNA, nucleosomes are the basic units of DNA packaging, consisting of DNA wrapped around a histone core. Both histones and nucleosomes play critical roles in gene expression and epigenetic inheritance.thisvsthat.io/histones-vs-nucleosomes

Histone - Wikipedia
In biology, histones are highly basic proteins abundant in lysine and arginine residues that are found in eukaryotic cell nuclei and in most Archaeal phyla. They act as spools around which DNA winds to create structural units called nucleosomes. Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled …
