Quiz

1. Which of the following mutations can still have normal functional proteins?
   a. Silent mutations

   b. Missense mutations

   c. Frame-shift mutations

   d. a and b
2. Does mutation in the targeting region affect the outcome of the protein?
   a. The protein functions in a normal fashion.

   b. The protein may fold properly, but it does not get to the right place.

   c. The protein can still find the target, but has trouble binding to its target.

   d. The protein has loss all function.
3. Which of the following statements is true?
   a. A frame-shift mutation occurs when there is a deletion of several bases in the mRNA.

   b. A silent mutation and a nonsense mutation would lead to the same result.

   c. A missense mutation from one acidic amino acid to another acidic amino acid would have no effect on the rate of reaction.

   d. A mutation in the catalytic region has minimal effect on the protein.
4. For a particular gene in a species, why are there more mutations in the noncoding than in the coding regions?
   a. DNA contains many duplications that can compensate for errors in the mutated regions.

   b. These mutations give rise to new functions and genetic diversity.

   c. Mutations in critical regions of DNA are not viable and can lead to failure in survival for an organism.

   d. There are an equal number of mutations in non-coding and coding regions of DNA.
