WebNov 1, 2006 · The two main candidates for the walking mechanisms of dimeric motors were inchworm or hand-over-hand. In the first case it is assumed that the first leading head advances one step which is followed instantaneously by the trailing head. In the hand-over-hand mechanism the second head advances two steps overpassing the first head. WebDec 19, 2003 · Two broad classes of model have been invoked to explain kinesin movement: hand-over-hand and inchworm. In hand-over-hand models, the heads exchange leading and trailing roles with every step, whereas no such exchange is postulated for inchworm models, where one head always leads. fishers high school boundary map
