A. Trypsin treated core histones quickly forms 30-nm fibers

B. Core histones lacking their amino-terminal tails are incapable of forming 30-nm fibers

C. Interaction between the positively charged amino terminus of histone H4 and a negatively charged region of the histone-fold domain of histone H2A is particularly important for 30-nm fiber formation

D. H2A that interact with the H4 tail are conserved across many eukaryotic organisms but are not involved in DNA binding or formation of the histone octamer.
