difference between nucleosome and chromatosome
Dear student.
The DNA (negatively charged) winds around histone octamer (positively charged) to form nucleosome. One nucleosome has approx. 200 bp of DNA. Nucleosomes in a chromatin resemble beads present on strings.
Chromatosome is a nucleosome that consists of a histone octamer, one molecule of linker histone such as Histone H1 and about 166bp of DNA. The linker histone is a binding agent, that holds the DNA together preventing its release.
Regards.
