WebJun 10, 2011 · The average diameter of B-DNA is about 2.0 nm. Other DNA conformations have diameters that range from about 1.8 to 2.3 nm (Wolfe 1993). The average distance between adjacent nucleotides in the same strand of DNA (the vertical rise) is between 0.321 to 0.337 nm (Wolfe 1993). WebZ-DNA is one of the many possible double helical structures of DNA. It is a left-handed double helical structure in which the helix winds to the left in a zigzag pattern, instead of to the right, like the more common B-DNA form. Z-DNA is thought to be one of three biologically active double-helical structures along with A-DNA and B-DNA .

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… Webdeoxyribonucleic acid.
