As nouns the difference between histone and elongator

is that histone is (biochemistry) any of various simple water soluble proteins that are rich in the basic amino acids lysine and arginine and are complexed with dna in the nucleosomes of eukaryotic chromatin while elongator is (protein) any of a family of proteins associated with histone acetylation.

As nouns the difference between histone and nonhistone

is that histone is (biochemistry) any of various simple water soluble proteins that are rich in the basic amino acids lysine and arginine and are complexed with dna in the nucleosomes of eukaryotic chromatin while nonhistone is a chemical compound that is not a histone.

As an adjective nonhistone is

not derived or obtained from a histone.

As nouns the difference between histone and bromodomain

is that histone is (biochemistry) any of various simple water soluble proteins that are rich in the basic amino acids lysine and arginine and are complexed with dna in the nucleosomes of eukaryotic chromatin while bromodomain is (biology) a protein domain that recognises acetylated lysine residues such as those on the n-terminal tails of histones, often a prerequisite for protein-histone association and chromatin remodeling.
