Consider the observations that a label on one head of a myosin V dimer moves in steps of 72 nm,but a label much nearer the myosin tail moves in steps of 36 nm.Discuss how these observations support a hand-over-hand mechanism rather than an inchworm mechanism of myosin V motility on an actin filament.
