WebDistributed melting bubbles are found to induce larger bending angles and decreased levels of stiffness in DNA than centrally located ones of comparable overall size. Our results indicate that spontaneous local opening-up of the DNA duplex could facilitate sharp bending of short DNA strands even in the absence of DNA binding proteins. WebSolution.
