For 10 points, name these positively-charged proteins around which DNA winds to form chromatin.
This protein's post-translational modifications are detected by bromodomains and chromodomains. The phosphorylation of serine-139 in one family of this protein functions as a marker for double-stranded breaks. HATs such as Gcn5 and Tip60 transfer acetyl groups to (*) lysines on the N-terminal tail of this protein. The "bead on a string" model describes how four distinct dimers of this protein assemble to form the core of a nucleosome, which can then bind to about 147 base pairs.
