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.
Purines, Pryimidine and Nucleotide are the subunits of DNA.
Nucleosome
this is incorrect question, because the size of the DNA is not specified. Without the DNA, it is chromosome > nucleosome > nucleotide. The actual DNA cannot be longer than a chromosome and nucleotide is a monomer of polymeric DNA, so DNA should be somewhere between chromosome and nucleotide.
Chromatin composed of tetramer of histones 2 copies each of Histone H2A, H2B, H3 and H4. DNA is bound on the nucleosome and uses 147 basepairs of DNA.
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.
Purines, Pryimidine and Nucleotide are the subunits of DNA.
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.
What are bead-like structures formed by DNA and histone molecules? Nucleosome

The small unit of chrosomorosomes is called genes.

The nucleosome. The nucleosome consists of DNA wound tightly around a protein called histone. This winding is sort of like coiling up a rope, and allows DNA to be packaged into a smaller space than would otherwise be achieved.
nucleosomes are DNA bound by histone.....
