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.
Chromatin is the âpackagedâ form of DNA in the nucleus and its regulation is central to transcription â creating the RNA copy of a DNA sequence. Chromatin helps assure that the DNA/RNA copy is precise â any deviation can result in stunted gene expression or proteins that no longer function properly.
