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.
DNA exists in Chromatin form in the nucleus. The chromatin condenses to form Chromosomes during cell division. Inside the nucleus. The chromatin in the nucleus forms a ' beads-on-string ' structure or Nucleosome. The 'beads' are octamer histone proteins and the 'string' is the double-stranded DNA.About 147 base pairs wrap around the 8-part histone protein to form a nucleosome. The nucleosomes condense to form a chromatin fiber.he chromatin in the nucleus forms a ' beads-on-string ' structure or Nucleosome.
