WebThis histone fold provides the basic unit of DNA packaging in eukaryotic cells. Outside of the region of the histone fold, the N-terminus of the histone forms a ‘tail’ comprising between 20 and 40 amino acids and having no defined secondary structure. ... These residues are located on the tails of histones that make up the nucleosome of ... WebHistone PTMs have been separately associated with either transcriptional activation or repression depending on the location of a single PTM site, but what type of effect distinct combinations of simultaneously occurring PTMs (Histone Codes) have upon transcriptional events remains unclear.
