A myosin molecule in the thick filaments can be considered a protein having a quaternary structural level. Which of the following best describes this structural level?

Question

Quizplus · Accepted Answer

The quaternary structure level of a protein refers to the arrangement of multiple protein subunits to form a larger functional protein complex. In the case of myosin, it consists of two heavy and two light polypeptide chains, and therefore can be considered a protein with a quaternary structural level. Choice A correctly describes the subunit composition of myosin. Choices B, C, and D refer to other aspects of myosin structure or function, but do not specifically address the quaternary structure level.
