Question

Which of the following statements about nucleosomes are correct? Choose all that apply. Most histones are small less than 150 amino acid residues and Arg. basic proteins rich in Lys The hstones H1, H2A, H28, H3, and H4 make up the nucleosome octamer that binds DNA ? DNA bindin histones enables overall positive supercoiling without enzymes that underwind the DNA helix. Partial enzymatic digestion of chromatin results in DNA fragments of about 101 bp. Histone proteins are positioned on DNA, in part, based on the abundance of clusters of GEC base pairs in DNA. Degradation of linker DNA yields DNA fragments of about 145 bp

Explanation / Answer

The fallowing statements are correct about the nucleosomes

Most of the histones are small less than 150 aminoacids add residues ), basic proteins rich in Lys and Arg

The histones H1,H2A,H2B,H3 AND H4make up the nucleosomes octomer 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 145 bp.
