Kinesin 1 and myosin II share each of the following features except
A)two heads.
B)dimers formed by heavy chain tails coiled around each other.
C)formation of bipolar filaments.
D)plus end directed motor activity.
E)ATPase activity.

Question

Quizplus · Accepted Answer

Kinesin 1 and myosin II both have two heads, form dimers with their heavy chain tails coiled around each other, have plus end directed motor activity, and exhibit ATPase activity. However, the formation of bipolar filaments is a feature specific to myosin II, not shared with kinesin 1. Kinesin typically does not form bipolar filaments; it moves along microtubules, while myosin II forms bipolar filaments and moves along actin filaments.
