Mutation Quiz

What is a mutation?

• A change in an organism's cell membrane

• A change in an organism's nucleic acids

• A change in an organism's protein structure

• A change in an organism's cell wall

Which type of mutation involves replacing one nucleotide with another?

• Frame shift mutation

• Deletion mutation

• Point mutation

• Insertion mutation

In a frame shift mutation, what occurs?

• One nucleotide replaces another

• Multiple nucleotides are substituted

• The DNA sequence remains unchanged

• The entire sequence shifts due to insertion or deletion

Which condition is an example of a point mutation?

• Cystic fibrosis

• Sickle cell anemia

• Color blindness

• Down syndrome

What is a missense mutation?

• A mutation that creates a stop codon

• A mutation that has no effect on protein function

• A mutation that changes one amino acid to another

• A mutation that deletes a nucleotide

When a mutation changes UAC to UAA, what type of mutation occurs?

• Silent mutation

• Missense mutation

• Frameshift mutation

• Nonsense mutation

What is a silent mutation?

• A mutation that creates a different amino acid

• A mutation that creates a stop codon

• A mutation that changes the reading frame

• A mutation that doesn't affect the amino acid produced

Which is NOT a common cause of mutations?

• Replication errors

• Protein synthesis

• Photosynthesis

• Mutagens

What is the role of DNA polymerase in relation to mutations?

• It causes mutations

• It proofreads and repairs DNA errors

• It creates frame shift mutations

• It promotes UV damage

Which of these is an example of a mutagen?

• DNA polymerase

• UV rays

• Amino acids

• Ribosomes
