They're called histone proteins. There are 8histones proteins in which a loop of DNA wraps around twice. Then another histone protein called the H1 linker binds them together.

What is the fundamental repeating unit of organization in a eukaryotic chromosome?
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 organic substance is a nucleosome composed of?
Nucleosomes are the basic repeating units of chromatin which is a combination of DNA and proteins that make up the content's of a cell's nucleus. Nucleosomes are made of a histone octamer which is comprised of two of the following histones: H2A, H2B, H3, and H4. The histone octamer is bound and wrapped around approximately 146 base pairs of DNA and an additional H1 histone is added and is wrapped around 20 more base pairs.
How many times does DNA loop around the histone proteins in the nucleosome?
Twice
A portion of a DNA molecule wound around a spool of histone protein is called a?
Such a structure is called a Nucleosome
DNA and histones form beadlike globule know as?
What are bead-like structures formed by DNA and histone molecules? Nucleosome

What are the subunits of DNA called?
Purines, Pryimidine and Nucleotide are the subunits of DNA.
True or false DNA is tightly wrapped around nucleosomes?
its quite intresting to kno dat in a single cell the length of DNA integrated is about 2metres or more. so to accomodate dat much length of smething it needs to b wrapped. it can can b thought of packing a heap of clothes in a small suitcase. So it has to be compacted to a level of packing called nucleosomes.
How many times does DNA loop around the histone proteins in the nucleosome?
Twice
What is the difference between nucleosome and chromatosome?
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.
A portion of a DNA molecule wound around a spool of histone protein is called a?
Such a structure is called a Nucleosome
What structure allows enormous lengths of DNA to be folded into the nucleus?
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.
How is a histone different from a nucleosome?
A nucleosome is a complex made of 8 histones with DNA wrapped around it approximately twice. Histone 1 probably serves to help stabilize the further wrapping of the nucleosomes into a solenoid. All of this helps to get 6 feet of DNA in a cell much less than a millimeter across.
DNA and histones form beadlike globule know as?
What are bead-like structures formed by DNA and histone molecules? Nucleosome
Dyad axis DNA nucleosome?
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.
What is the Structure of histones and non histones?
Histones are the major protein structure of chromosomes. The DNA is wrapped twice around a histone octamer to create a nucleosome, which are assembled six at a time to make a Solenoid. Solenoids coil into a scaffold, which is then coiled itself to make the chromosomal matrix.
