A normal muscle cell produces the myosin protein, which allows muscles to contract. You discover a single muscle cell that has tRNAs that do not bind to amino acids. Will the myosin gene be expressed in this muscle cell? Why or why not?

Question

Quizplus · Accepted Answer

If tRNAs cannot bind to amino acids, then translation cannot occur, and the myosin protein cannot be produced. Therefore, the myosin gene will not be expressed in this muscle cell. Choice A is incorrect because not all cells in the body express the myosin gene at all times. Choice C is incorrect because transcription alone does not result in protein production. Choice D may or may not be true, but it does not address the question of whether the myosin gene will be expressed.
