Nucleosome with approximately 200bp of DNA and the histone octamer with H1 protein. but in chromatosome, the linher DNA of approximately 45bp is absent.
What else can I help you with?
What is the difference between chromosomes and nucleosomes?
Chromosome Nucleosome
How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?
Is nucleosome equals to chromosome?
no
A portion of a DNA molecule wound around a spool of histone protein is called a?
Such a structure is called a 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 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.
Bead-like units composing chromosomes?
Nucleosome
What is the description of a chromatin fiber?
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 how many histones within its core?
A nucleosome contains two copies each of four core histone proteins: H2A, H2B, H3, and H4.
What is the order of size between codon chromosome nucleotide DNA and 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.
The basic unit that structurally organizes a eukaryotic chromosome is?
nucleosome
