Nucleosides - Study guides, Class notes & Summaries

Step 1 First Aid - Biochemistry Chromatin structure Answer- Negatively charged DNA loops twice around histone octamer (2 each of the positively charged H2A, H2B, H3, and H4) to form nucleosome bead. H1 ties nucleosomes together in a string. (Think of "beads on a string"; H1 is the only histone that is not in the nucleosome core.) In mitosis, DNA condenses to form mitotic chromosomes. <img src="66a - Euchramatin strxr.JPG" /> Heterochromatin Answer- Condensed, transcriptiona...
