For the first time, researchers have demonstrated how mechanical forces affect gene expression by showing that RNAP polymerase remains on the DNA template and can be pulled to start a subsequent cycle of transcription. This force-directed recycling mechanism can change the relative abundance of adjacent genes.

Researchers have discovered a new mechanism underlying the control of gene expression in all living organisms. Transcriptional pausing by RNA polymerase provides a 'roadblock' to help regulate gene expression levels, which could aid our understanding of antibacterial drugs and future synthetic gene design.
