Question

The length of DNA helix in a typical nucleosome is (A) 3.2×106 bp (B) 6.6×109 bp (C) 200 bp (D) 1000 bp

The DNA is wound around the histone proteins to form the nucleosome. The histone molecule is a complex made up of eight histone proteins - two molecules each of histones H 2 A , H 2 B , H 3, and H 4. In every nucleosome, around 200 bp of DNA helix is wrapped around the histone octamer.
