Diameter of dna in nm

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… WebOct 1, 2004 · By combining these two elements, we have already produced ∼1-nm diameter pores that are smaller in diameter than DNA in solution, through membranes ∼5–50-nm …
