A. It is formed by the further folding of 10nm solenoidal fiber.
B. The central axis of loop model consists of non-histones.
C. 16 loops are connected with non-histone and radially arranged in a plane, which forms a micro-strip.

What’s the following statement about the effect of modification in histone terminal on nucleosome stability is NOT correct:____
A. The positive charged amino acid residues in histone terminal benefit for the stable connection of histone and DNA.
B. The acetylation of Lys residue in histone terminal make the packaging of 10nm fiber more closer.
