Problem 2: Single Kind of Motor

Explain how a single kind of "motor" can cause movement of a wide variety of substances, including vesicles, chromosomes, proteins, etc.

A.	Nature has evolved many different mechanisms or motor proteins, each unrelated to the other and with independent mechanisms/including vesicles, chromosomes, proteins, etc.
B.	Multi-gene families of motor proteins have the mechanism for moving along microtubules in common and have the other part of the same protein altered to allow binding to a variety of substances.
