We describe a potential molecular mechanism explaining how DNA methylation contributes to biological regulation. Using molecular dynamics together with a new torsional restraint, we identify the impact of methylation on DNA response to torsional stress. We observe that, depending on the sequence, DNA methylation hinders overwinding or underwinding molecular transitions.
