What else can I help you with?
The spools from which the DNA unwinds is made of what?
DNA is found on spools made of histones. These are groups of basic proteins found in the chromatin and involved in the packaging of DNA.
What is the protein around which chromosomal DNA is coiled?
The protein around which chromosomal DNA is coiled is called histones. Histones help in organizing DNA into structural units called nucleosomes, which then further coil and condense to form chromatin fibers.
What is the DNA called when it is found loose in the nucleus and is wrapped around histones?
The DNA found wrapped around histones in the nucleus is called chromatin. Chromatin consists of DNA and proteins, including histones, which help to package and organize the DNA in the cell. This compact structure allows for efficient storage and regulation of gene expression.
Does histones and DNA molecules relate to each other?
Histones are a part of DNA. Histones are actually 8 molecule of proteins joined together and the DNA strand wraps around the the histone in a circular manner. Histones are present on the DNA strand at regular intervals.
What role do histones play in a cell?
DNA strands are wrapped around the histones. In order for DNA to be accessible, histones must be modified (acetylation). If the histones are "protected" at a particular locus from modification, the genes are silenced and cannot be expressed.
To help with biology homework what are histones?
Histones are proteins found in eukaryotic cell nuclei. They are high in alkaline. Histones package and order the DNA into units that are called nucleosomes.

DNA is found on spools made of histones. These are groups of basic proteins found in the chromatin and involved in the packaging of DNA.
What are chromatin proteins called?
Chromatin is the name of the mixture of DNA and proteins that are found in the nucleus of a cell. Depending on the stage of the cellular cycle, the chromatin may be structured differently, ranging from loosely to tightly structured.
What is the protein around which chromosomal DNA is coiled?
The protein around which chromosomal DNA is coiled is called histones. Histones help in organizing DNA into structural units called nucleosomes, which then further coil and condense to form chromatin fibers.

The DNA found wrapped around histones in the nucleus is called chromatin. Chromatin consists of DNA and proteins, including histones, which help to package and organize the DNA in the cell. This compact structure allows for efficient storage and regulation of gene expression.
Chromatin contains proteins called?
The proteins inside a chromosome are called Histones.
Where and in what form is eukarytoic DNA found?
Location: within the nucleus Form: Highly condensed and super coiled. Found associated with proteins called histones
What chemicals are found in chromatin?
The material of CHROMOSOMES. It is a complex of DNA; HISTONES; and nonhistone proteins (CHROMOSOMAL PROTEINS, NON-HISTONE) found within the nucleus of a cell.
What proteins are found in chromatin?
You may be looking for the term "histones," which are the protein component of chromatin (which comprises chromosomes).Histones are proteins around which DNA winds, making it dense and compact; this results in the denser form of chromatin, known as "heterochromatin." Histones thus play a role in regulating the expression of genes (because they cannot be expressed whilst compacted). When histones are modified, they can change shape or charge and release the tightly-wound DNA so that the genes can be expressed; this looser form of chromatin is known as "euchromatin."Together, heterochromatin and euchromatin make up chromosomes.http://en.wikipedia.org/wiki/Histone
Do eukaryotes have histones?
Yes, eukaryotes have histones, which are proteins that help in packaging and organizing DNA within the nucleus. Histones associate with DNA to form nucleosomes, the basic repeating unit of chromatin.
Does histones and DNA molecules relate to each other?
Histones are a part of DNA. Histones are actually 8 molecule of proteins joined together and the DNA strand wraps around the the histone in a circular manner. Histones are present on the DNA strand at regular intervals.
When does DNA begins to condense with help of structural proteins like histones?
as soon as histones are put in solution with DNA it begins to condense. Just by being there the positively charged histones are attracted to the negatively charged DNA. DNA wraps around histones and other structural proteins condensing to metaphase chromosomes.
