Mars2501 [29]

Answer:

Option E, ALL OF THE ANSWERS ABOVE ARE TRUE OF MYOSIN.

Explanation:

Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes.

Muscle myosin is a heterohexamer consisting of two MyHCs and two associated non identical pairs of myosin light chains.

Myosin is a common protein found in the muscles which are responsible for making the muscle contract and relax. It is a large, asymmetric molecule, and has one long tail as well as two globular heads. If dissociated, it will dissociate into six different polypeptide chains. Myosin also aggregates to form thick filaments.

Since all the options on statements about myosin are true, therefore, the option that best suits the question is option E, ALL OF THE ANSWERS ABOVE ARE TRUE about myosin.
