Read each question carefully and answer to the best of your ability. For multiple-choice questions, circle the correct option. For fill-in-the-blank and short-answer questions, write your answers in the space provided.
1. What is a genetic mutation?
A change in the protein structure
A permanent alteration in the DNA sequence
The process of DNA replication
The expression of a gene
2. Which type of mutation involves the substitution of a single nucleotide?
Frameshift mutation
Point mutation
Deletion mutation
Insertion mutation
3. A mutation that results in a premature stop codon is called a mutation.
4. are agents that can cause genetic mutations.
5. Explain the difference between a silent mutation and a missense mutation.
6. All genetic mutations are harmful.
True
False
7. Mutations can be inherited from parents.
True
False
8. Observe the image below showing a DNA double helix. How does a point mutation at a specific base pair, for example, changing Adenine (A) to Guanine (G), affect the overall structure and function of the DNA if it occurs in a coding region?
Match each type of mutation with its description.
9. Deletion
a. A segment of DNA is duplicated
10. Insertion
b. One or more nucleotides are removed
11. Duplication
c. One or more nucleotides are added
12. Discuss how genetic mutations contribute to genetic variation within a population and their role in evolution.
