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.

What is the role of proteins in allowing DNA to fit in a cell?
The protein histone, and attendant proteins, spool the DNA tightly around their complexes and then further wind these complexes into tighter and tighter shapes. About two meters worth of DNA per cell is held in these histone complexes.
How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?
What type of phosphorylation does not require a membrane?
oxidative phosphorylation
What is a small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in it chromatin structure?
histone
Another name for electron transport chain is?
oxidative phosphorylation
What is the role of water in cyclic photo phosphorylation?
It provides electrons and protons.
What is the attachment of a phosphate group to a molecule called?
phosphorylation

What are the sources of histone binding protein RbAp48?
what are the sources of histone binding protien RbAp48
What is the major role of oxidative phosphorylation in cellular respiration?
To produce ATP from the high energy electron carriers NADH and FADH2.
How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?
What is the major function of a histone protein?
Alkaline proteins found in eukaryotic cell nuclei.
What type of phosphorylation does not require a membrane?
oxidative phosphorylation
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 is a small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in it chromatin structure?
histone
What are nonhistones?
histone are nonprotienous
Does ATP contain histone?
No, it does not.
