Mutations Quiz

What is a mutation?

• A. A type of protein

• B. A change in an organism's DNA

• C. A viral infection

• D. A cellular organelle

Where can mutations produce changes?

• A. In a single gene

• B. In whole chromosomes

• C. Both A and B

• D. Only in non-genetic material

What is caused by mutations in genes?

• A. Dishonesty

• B. Cancer

• C. Kindness

• D. Hatred

What is an example of a condition caused by mutations at the chromosomal level?

• A. COVID

• B. Down syndrome

• C. Tuberculosis

• D. Malaria

What happens once a mutation occurs in one cell?

• A. It affects only that single cell

• B. That cell always undergoes apoptosis

• C. All cells that come from the original cell have the mutation

• D. It causes the organism to become immune to diseases

Can mutations be passed down from one generation to the next?

• A. Yes, always

• B. No, never

• C. Only through the maternal line

• D. Yes, they can be passed down

What is a point mutation?

• A mutation where a segment of DNA is inverted

• A mutation where a segment of DNA is deleted

• A mutation where one nucleotide is substituted for another

• A mutation where a segment of DNA is duplicated

What is usually responsible for fixing point mutations?

• Ribosome

• DNA ligase

• DNA polymerase

• RNA polymerase

What can be the consequence of a point mutation if it is not fixed?

• It never affects the protein

• It changes every amino acid in the polypeptide

• It usually changes one amino acid in the polypeptide

• It always stops protein synthesis

Where can a point mutation change the entire protein?

• In a regulatory sequence

• In the middle of a coding sequence

• In a start or stop codon

• In a non-coding region
