Question

Which of the following statements about nucleosomes are correct? Choose all that apply. Histone proteins are positioned on DNA, in part, based on the abundance of clusters of A=T base pairs in DNA. Partial enzymatic digestion of chromatin results in DNA fragments of about 1.00 x 10^2 bp. Most histones are large (more than 250 amino acid residues), acidic proteins rich in Lys and Arg. The histones H2A, H2B, H3, and H4 make up the nucleosome octamer that binds DNA. DNA binding to histones enables overall positive supercoiling without enzymes that underwind the DNA helix. Degradation of linker DNA yields DNA fragments of about 200 bp.
