What makes the outside of the DNA molecule?
histone proteins envelope DNA molecules inside the cell.
A type of protein found in eukaryotic chromosomes but not prokayotic chromosomes is?
This type of protein is a histone.
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?
Which nucleic acid molecule contains protein?
Nucleic acid and proteins are different macromolecules that does not contain the other. However, there are some cases where the protein histone is wrapped by the DNA which then coils to form chromosomes.
What makes the outside of the DNA molecule?
histone proteins envelope DNA molecules inside the cell.
A portion of a DNA molecule wound around a spool of histone protein is called a?
Such a structure is called a Nucleosome
A type of protein found in eukaryotic chromosomes but not prokayotic chromosomes is?
This type of protein is a histone.
A type of protein found in eukaryotic chromosomes but not prokaryotic chromosomes is?
Histone
What is the diameter of the DNA molecule?
The diameter of the alpha helix structure of DNA is 2nm, the diameter after having wrapped around the first histone is 11nm. That string wraps around another histone forming a 30nm chain, and so forth until you reach the chromasomal structure of roughly 700nm.
What are the sources of histone binding protein RbAp48?
what are the sources of histone binding protien RbAp48
What does the term 'histone acetylation' means?
Histones are proteins that organize DNA in the chromatin of eukaryotes (cells that have membrane enclosed nuclei). Acetylation means the introduction of acetyl group to a molecule. In essence, Histone Acetylation removes the positive charge on the histones which, in turn, causes a decrease in the interaction with negatively charged phosphates in DNA.
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 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 are nonhistones?
histone are nonprotienous
Does ATP contain histone?
No, it does not.
