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… WebNo, it is not possible to see a single DNA molecule with the naked eye because the diameter of the DNA double helix is only 2 nanometers, which is much smaller than the resolution of the human eye. so we can not see DNA molecule every human human eye can resolve objects that are around 0.1 millimeters in size, which is approximately 50,000 …
