Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles
EleoNora [17]

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

why does frameshift mutation usually cause more defects during protein synthesis than a point mutation
Anuta_ua [19.1K]

I believe this is because the frameshift mutations can affect many amino acids. 

Frame shift mutation is produced by either insertion of deletion of one or more new bases. Since the reading frame begins at the start site, any mRNA produced from mutated DNA sequence will be read out of frame after the point of the insertion or deletion, thus producing a nonsense protein.
