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.
One of the main functions of chromatin is to reduce the size of DNA so it can fit in the cell. It does this by wrapping a DNA molecule tightly around proteins called histones. The histones are there to maintain the structure of the chromosome. Other functions of chromatin include reinforcing DNA molecules for mitosis, preventing DNA damage, and helping to control DNA replication.
