Strand separation
Web1 Feb 2024 · Studies of several helicases have identified strand-separating “pin” structures that are positioned to intercept incoming dsDNA and promote strand separation during helicase translocation. However, pin structures vary among helicases and it remains unclear whether they confer a conserved unwinding mechanism. Weboccurrences of the opening angles θacross the range of DNA strand separation 0.0˚A - 2 .0˚A and estimate the speed at which the strand separation occurs. The MD system is constructed of 14 base pairs within a double strand of DNA, initially in equilibrium and an aqueous environment. In the quantum mechanical investigations, the opening angle

Web17 Nov 2012 · Measurements stretching DNA mechanically to the point of strand separation were carried out with a new chip technology, molecular force assay (MFA), that permits one to stretch and rupture apart thousands of DNA double strands organized by methylation type on spots on the chip with a fluorescent signal readout. WebGiven the challenges of DNA strand separation and its vital importance, it is not surprising that cells have developed many strategies for promoting unlinking. We summarize seven different factors that contribute to strand separation and chromosome segregation. These are: (1) supercoiling promotes unlinking by condensation of DNA; (2) unlinking ...
