Concept explainers
To explain: Why would no bending motion occur at the cilium when all dynein molecules were active at the same time.
Introduction: Dyneins are the family of minus end–directed microtubule motor protein. They are composed of two or three heavy chains and large variable number of associated light chains. The specialized arrangements of the microtubules are remarkably similar in their organization. Cilium possesses a central bundle of microtubule called axosome.
To explain: The pattern of dynein activity accounts for the bending of a cilium in one direction.
