Nucleosome structure


Histones: H2A yellow and orange
H2B green and light blue
H3 red and magenta
H4 blue and cyan

The modifications occur on the N-terminal tails of the histones, and are not shown here.

Structure of the Drosophila nucleosome core particle highlights evolutionary constraints on the H2A-H2B histone dimer.
