Part of Chromatin. Smaller units made of DNA & histone octamers (8). 2 of each: H2A, H2B, H3, H4, all attached to the larger H1.
the number of histone subunits in a nucleosome is?
The Nucleosome has an approximate two fold axis of symmetry which is called the Dyad Axis. So when you rotate the Nucleosome by 180 degree you would observe the similar view of Nucleosome before the rotation.
Chromosome Nucleosome
A chromatin fiber is the point at which DNA in chromatin is higher then the nucleosome. Chromatin fibers occur when the linear array of the nucleosome fold into a tighter fiber.
A nucleosome contains two copies each of four core histone proteins: H2A, H2B, H3, and H4.

no
Such a structure is called a Nucleosome

Histone H1Histone H1 is found in a chromatosome but not in a nucleosome. Nucleosome with approximately 200bp of DNA and the histone octamer with H1 protein. but in chromatosome, the linher DNA of approximately 45bp is absent.
The nucleosome is the basic unit that organizes the structure of an eukaryotic chromosome. The nucleosome is DNA wrapped around histone proteins which allows the DNA to condense into chromosomes.
