c

Chromosomal mutation

d

Duplication mutation

2. What is the primary role of DNA repair mechanisms?

a

To introduce new mutations

b

To prevent DNA replication

c

To correct errors in DNA sequence

d

To synthesize new proteins

1. A   mutation is a type of gene mutation that involves the insertion or deletion of a nucleotide in the DNA sequence.

2.   are agents that can cause mutations in DNA.

3. The ultimate source of all new alleles in a population is  .

1. Explain the difference between a somatic mutation and a germline mutation. Provide an example of the potential impact of each.

2. Describe how a silent mutation differs from a missense mutation and a nonsense mutation. Which type is most likely to have a significant impact on protein function?

1. All mutations are harmful to an organism.

T

True

F

False

2. Mutations can occur spontaneously during DNA replication.

T

True

F

False

Observe the diagram of the DNA double helix below. If a point mutation occurred at the indicated base pair, changing Adenine (A) to Guanine (G), what would be the likely consequence for the complementary strand during replication?
