Understanding Mutations in Biology

What is the primary role of mutations in the process of evolution?

• To stabilize genetic sequences

• To eliminate genetic diversity

• To create genetic variation

• To prevent genetic replication

Which type of mutation involves a change in the nucleotide sequence?

• Gene duplication

• Translocation

• Nucleotide mutations

• Chromosomal mutations

What is a silent mutation?

• A mutation that stops protein synthesis

• A mutation that does not change the amino acid sequence

• A mutation that changes the amino acid sequence

• A mutation that deletes a nucleotide

In a missense mutation, what happens to the amino acid sequence?

• It remains unchanged

• An amino acid is replaced by another

• A nucleotide is deleted

• It is replaced by a stop codon

What is the consequence of a nonsense mutation?

• The protein is duplicated

• The protein remains unchanged

• The protein is longer than intended

• The protein is shorter than intended

What causes a frame shift mutation?

• Duplication of a gene

• Translocation of a chromosome

• Insertion or deletion of a nucleotide

• Substitution of a nucleotide

How does a frame shift mutation affect the reading frame?

• It stabilizes the reading frame

• It shifts the reading frame

• It deletes the reading frame

• It duplicates the reading frame

What is extensive missense?

• A single amino acid change

• Multiple amino acid changes

• No change in amino acids

• A stop codon formation

What should students know about mutations for AP Biology?

• The categorization and effects of mutations

• The history of mutations

• Only the types of mutations

• Only the effects of mutations

What is the impact of non-conservative missense mutations?

• They duplicate the protein

• They cause a change in protein structure

• They have no impact

• They stabilize the protein
