DNA is a relatively rigid polymer, typically modelled as a worm-like chain. It has three significant degrees of freedom; bending, twisting, and compression, each of which cause certain limits on what is possible with DNA within a cell. Twisting-torsional stiffness is important for the circularisation of DNA and the orientation of DNA bound proteins relative to each other and bending-axial stiffness is important for DNA wrapping and circularisation and protein interaction… WebI would like to know the physical size [(hydrodynamic) diameter, e.g. from Dynamic Light Scattering (DLS), or from Atomic Force Microscopy(AFM)] of plasmid DNA (around 8-10 kbp) in its supercoiled ...
