Question

This illustration shows the protein structure of the sodium channel protein that is involved in TTX susceptibility and resistance in garter snakes. If there are mutations at one of the sites identified by vertical red arrows, the snake can resist the effect of the toxin. Assume there is a population of toxic newts and there are snakes that do not initially have mutations that confer resistance to the toxin. If a mutation happens in this gene, you expect that it is most likely to A occur O at one of the sites that confer resistance (where the arrows are) somewhere else in the gene that does not confer resistance O.at the amino terminal end (where the NH2 is) because the chemistry makes the front end of the gene less stable it is impossible to choose any of the options because mutation is unpredictable

Explanation / Answer

Option 4 is the correct answer.

It is impossible to choose any of the options because mutation is unpredictable. By it's definition itself, mutation is an unpredictable occuring in the genetic material of an organism. It might be beneficial such as providing resistance or it might not be. Natural mutations are notorious for their unpredictability, however, mutations can be targeted in-vitro.
