Supercoiling DNA with a free end
Daniela Moretti, Giuseppe Gonnella, Antonio Suma +3
In this work, we combine coarse-grained Brownian dynamics simulations and mean-field theory to study supercoiling dynamics, as well as the steady-state profiles of twist and writhe…

When Knots are Plectonemes
Fei Zheng, Antonio Suma, Christopher Maffeo +6
The transport of DNA polymers through nanoscale pores is central to many biological processes, from bacterial gene exchange to viral infection. In single-molecule nanopore sensing,…

Unzipping of knotted DNA via nanopore translocation
Antonio Suma, Cristian Micheletti
DNA unzipping by nanopore translocation has implications in diverse contexts, from polymer physics to single-molecule manipulation to DNA-enzyme interactions in biological systems.…
