A Histone Core is a group of Histone Proteins, mainly used in eukaryotes to package DNA strands into Nucleosomes. (Think of it like a spool for the DNA to wrap around, to be easily stored on a shelf)

What is DNA wrapped around in a nucleosome?
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 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.
What is composed of DNA and proteins?
chromatids/chromatin.
Eukaryotic chromosomes contain both DNA and protein tightly packed together to form a substance called?
The complex of both histone and non-histone chromosomal proteins and DNA is known as chromatin.
In eukaryotes what is active transcription generally associated with?
Both euchromatin and histone acetylation.

A special protein that forms part of the structure of a chromosome?
Most notably, the Histone proteins which, along with Dna, form the core of the 10 nm fibers.
What are the sources of histone binding protein RbAp48?
what are the sources of histone binding protien RbAp48
What is role of histone phosphorylation?
Since phosphate groups have a negative charge, adding them to histone tails neutralizes them and probably reduces their affinity for DNA. It might contribute to transcription because it stimulates histone acetyltransferases which cause histone acetylation and enhance transcription.
How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?

What are nonhistones?
histone are nonprotienous
Does ATP contain histone?
No, it does not.
What do chromosomes use histone proteins for?
Chromosomes, as a thread, use histone protein cores as spools that they use to wrap around and, hence, condense.
What protein does chromatin coils around?
histone
What does chromain contain?
DNA and Protein Histone
