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.
These strands, called chromatin, contain the genetic material, the instructions that direct the functions of a cell. For example, the instructions in the chromatin ensure that leaf cells grow and divide to form more leaf cells. The genetic material is passed on to each new cell when an existing cell divides. Bacterial cells do not have nuclei, so you are correct, their DNA is located in the cytoplasm.
