Abstract

Abstract : Trajectories of azobenzene incorporated DNA conjugated microtubules are regulated by photoirradiation in a reversible manner. Abstract : We regulate the persistency in motion of kinesin-driven microtubules (MTs) simply using a photoresponsive DNA ( p DNA) and ultraviolet (UV)-visible light. The path persistence length of MTs, which is a measure of the persistency in their motion, increases and decreases upon illuminating the MTs with UV and visible light respectively. Moreover, p DNA is found to work as a shield for MTs against damage under UV irradiation.
