Abstract
An interplay between DNA-dependent biological processes appears to be crucial for cell viability. At the molecular level, this interplay relies heavily on the communication between DNA-bound proteins, which can be facilitated and controlled by the dynamic structure of double-stranded DNA. Hence, DNA structural alterations are recognized as potential tools to transfer biological information over some distance within a genome. Until recently, however, direct evidence for DNA structural information as a mediator between cellular processes was lacking. This changed when the concept of transient waves of DNA supercoiling, induced by proteins tracking along the right-handed DNA double helix, came into the limelight. Indeed, a number of observations now suggest that helix tracking-induced DNA structural information might be exploited to participate in the regulation of a variety of DNA transactions in vivo.
