Dna radius of gyration

WebThe DNA radius of gyration is intimately related to the DNA persistence length, namely the correlation length of the tangent−tangent correlation function, tt() (0) exp( / )ssL· = − p(1) where t(s) is the unit vector tangent to the chain at the point of curvilinear index s. The persistence length, L p WebThe circularity and the radius of gyration explain the size and shape of the cavity of the ring, and the flip angle and important distances describe the conformational changes and the flexibilities of the HP groups. The results show that HPβCDs have a more pronounced conical shape than βCD; however, cavity self-closure occurs because some ...
