Lesson Summary. Chromatin is the special complex of DNA and protein that condenses the genome so that it can be packed into the tiny nucleus. First, DNA is wrapped around histone proteins. Then, a group of histones comes together to form a nucleosome. Finally, the string of nucleosome beads is coiled to condense the DNA even further.
Other scaffold proteins are also involved. The result is a structure coiled many times back on itself, so that very very long strands of DNA can fit in the small spaces of the cell nucleus. The substance chromosomes are made of (the DNA + histones, independent of its larger structure) is called chromatin.
