These proteins are very highly evolutionarily conserved, and in their most notable role, these proteins function as an octomer and form a structure often described as "beads on a string.
The N-terminus of these proteins is composed of many lysine and other positively charged basic residues, and the genes that code for these proteins are thought to have very few introns. These proteins are arranged in either a zig-zag or spherical arrangement to form the thirty nanometer fibers, which is eventually densely packed in heterochromatin. These proteins are very highly evolutionarily conserved, and in their most notable role, these proteins function as an octomer and form a structure often described as "beads on a string." Those beads are called nucleosomes. For 10 points, name these proteins around which DNA is wound.
