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.
The genes within these chromosomes are the cell's nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression âthe nucleus is, therefore, the control center of the cell.he function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression âthe nucleus is, therefore, the control center of the cell.
