Read each question carefully and answer to the best of your ability. Refer to your notes and textbook if needed.
1. Which type of mutation involves the substitution of a single nucleotide base?
Frameshift mutation
Point mutation
Chromosomal mutation
Deletion mutation
2. A mutation that results in a premature stop codon is called a:
Missense mutation
Silent mutation
Nonsense mutation
Insertion mutation
3. A is any change in the DNA sequence of an organism.
4. Environmental factors such as radiation and certain chemicals that can cause mutations are called .
5. A mutation that does not change the amino acid sequence of a protein is known as a mutation.
6. Briefly explain the difference between a somatic mutation and a germline mutation. Which type is heritable?
7. Describe at least two potential effects of a frameshift mutation on the resulting protein.
8. All mutations are harmful to an organism.
True
False
9. DNA repair mechanisms can correct some types of mutations.
True
False
10. Observe the image of a DNA double helix below. If a point mutation occurred where the Adenine (A) at position 3 on the top strand was replaced by a Guanine (G), how would this affect the complementary strand and the possible amino acid sequence?
