radioactive man, a comic - book superhero, gained his abilities by falling into a vat of industrial toxic waste. is this a likely outcome?
a yes, because mutations can be helpful, harmful, or neutral.
b no, because most mutations are neutral.
c no, because toxic waste is not mutagenic.
d no, because so many mutations would probably cause cancer or other disease.
question 22

the type of mutation where a single letter in a sequence is changed but does not result in a change in the amino acid sequence of the protein:
a missense mutation
b silent mutation
c nonsense mutation
d frameshift mutation
e inversion mutation

Explanation:

For question 21, industrial toxic waste can cause mutations, but they are usually harmful like cancer - causing rather than giving super - abilities. For question 22, a silent mutation is a point mutation that changes a single nucleotide but does not change the amino - acid sequence of the protein due to the degeneracy of the genetic code.

Answer:

Question 21: D. No, because so many mutations would probably cause cancer or other disease.
Question 22: B. silent mutation
