Vedclass · Answer

(C) In the structure of nucleosomes,the histone octamer is wrapped by $DNA$. The $DNA$ makes approximately $1.65$ turns around the histone core. Studies on the interaction between histone proteins and $DNA$ show that the $DNA$ helix interacts with the histone surface,and the orientation of the $DNA$ relative to the histone core involves specific angular positioning. Specifically,the $DNA$ path around the histone octamer is oriented at an angle of $45^o$ to the helix axis.

Histone occupies the major grooves of $DNA$ at an angle of
