A sequence environment modulates the impact of methylation on the torsional rigidity of DNA
Chemical Communications, 2018 We explain, with atomic-level detail, how DNA methylation may contribute to the regulation of biological processes. We show that DNA sequence environment modulates the impact of methylation on the physical properties of the double helix.
