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… WebA simplistic answer would be to look at the size of bacteriophages, which hold genomes somewhat larger than 7 kb (Lambda for example is a bit less than 50kb) and have capsid …
