The Helix Twist: Damage and Repair Follows the DNA Minor Groove

Cell. 2018 Nov 1;175(4):902-904. doi: 10.1016/j.cell.2018.10.034.

Abstract

Mutation frequencies vary along the genome, but the factors determining this variability are only partially understood. Pich et al. unravel a ∼10 bp periodicity in mutation rates at nucleosome-proximal regions that follows minor groove orientation. Opposing differential DNA damage and repair processes could shape genetic divergence irrespective of selection.
