Caption: This artist's illustration shows a portion of the genome. A long DNA molecule (red cord) is wrapped up into nucleosome structures with a histone-protein core (white spheres). The gateway to gene transcription spans the control switch (coils) on the left nucleosome to the beginning of the gene (green arrow) on the right nucleosome.
