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.
What is the size of nucleosome?
A nucleosome is approximately 10 nm in size and consists of DNA wrapped around a core of histone proteins. It is a fundamental unit of chromatin structure in eukaryotic cells.
What structure will the chromatin become in mitosis?
The chromatin in the cell becomes chromosomes in prophase, the first stage of mitosis. The chromatin coils tightly together to form into separate chromosome strands during this phase.
What are beads in unfolded chromatin?
Beads in unfolded chromatin refer to nucleosomes, which are the basic repeating units of chromatin structure. Each nucleosome consists of DNA wrapped around a core of histone proteins, resembling beads on a string. This structure helps to condense and organize DNA within the cell nucleus.
In a histone core does DNA wrap around a nucleosome cord?
Yes, in a histone core, DNA wraps around a structure called a nucleosome. Each nucleosome consists of a segment of DNA wrapped around a core of histone proteins, forming a fundamental unit of chromatin. This wrapping helps package the DNA into a compact, organized structure within the nucleus, allowing for efficient storage and regulation of genetic information.
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.
Which of the following represents the order of increasingly higher levels of organization of chromatin?
nucleosome, 30-nm chromatin fiber, looped domain
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.
How is DNA packaged into a chromosome?
DNA is packaged into a chromosome by wrapping around proteins called histones, forming a structure known as chromatin. This chromatin then coils and condenses to create the compact structure of a chromosome.

A nucleosome is approximately 10 nm in size and consists of DNA wrapped around a core of histone proteins. It is a fundamental unit of chromatin structure in eukaryotic cells.

What is the highest level of chromatin organisation?
nucleosome, 30-nm chromatin fiber, looped domainLook at the effect the earth's Schumann Resonance on human DNA.Also, how the Earth's resonance in increasing.

A chromosome is made up of even smaller bodies?
It is made up of genes.
Are Barr body projection of extra chromatin on the an X chromosome?
Yes, a Barr body is an inactivated X chromosome seen in the nuclei of female mammals. It appears as a small, dense, dark-staining body due to the condensation of the chromatin, which is a result of X chromosome inactivation to equalize gene expression between males and females.
Does a chromosome contain histone?
Histones are proteins that aid the condensation of the DNA. Condensation makes the DNA more compact so it would fit in the cells. In this compaction process, DNA is winded around these proteins.
