Twin Supercoil Domain couples the dynamics of molecular motors and plectonemes during bacterial DNA transcription and replication
Marc Joyeux
The genomic DNA of most bacteria is significantly underwound, which constrains the DNA molecule to adopt a branched plectoneme geometry. Moreover, biological functions like replica…

Models of topological barriers and molecular motors of bacterial DNA
Marc Joyeux
Bacterial genomes are partitioned into kilobases long domains that are topologically independent from each other, meaning that change of DNA superhelicity in one domain does not pr…
