Which of these statements about nucleosomes are correct?
Most histones are small (less than 150 amino acid residues), basic proteins rich in Lys and Arg.
Degradation of linker DNA yields DNA fragments of about 145 bp.
The histones H1, H2A, H2B, H3, and H4 make up the nucleosome octamer that binds DNA.
DNA binding to histones has the same effect as positive supercoiling.
Partial enzymatic digestion of chromatin results in DNA fragments of about 122 bp.
