How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?
Dyad axis DNA nucleosome?
In a DNA nucleosome, the DNA double helix is wrapped around a core of histone proteins forming a structure known as a nucleosome. The dyad axis refers to the central point of symmetry within the nucleosome where the DNA helix is bent and connected by a histone protein. This bending allows for tight packaging of DNA while still maintaining accessibility for regulation and transcription.
What is the difference between chromosomes and nucleosomes?
Chromosome 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.
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

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.
What is the fundamental repeating unit of organization in a eukaryotic chromosome?
The fundamental repeating unit of organization in a eukaryotic chromosome is the nucleosome. A nucleosome consists of DNA wrapped around a core of histone proteins. Multiple nucleosomes are connected by linker DNA to form chromatin fibers.
Bead-like units composing chromosomes?

The basic unit that structurally organizes a eukaryotic chromosome is?
nucleosome
What is larger a nucleosome or chromosome?
A chromosome is made up of many genes.
