Diameter of dna in nm
WebThe plane of the base pairs in B-DNA is tilted about 6 degree with respect to the helix axis. One complete turn of the double helix is 3.4 nm long and each of which has 10.5 base pairs, the distance between two consecutive base pairs 0.34 nm. Correct answer is B. Solve any question of Molecular Basis of Inheritance with:- Patterns of problems > WebDNA is a molecule composed of two polynucleotide chains that coil around each other to form a double helix. The DNA double helix has a diameter of 2 nm. The space between two base pairs is 0.34 nm. The distance between each helix turn is 3.4 nm (including ~10 base pairs).

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…
