Gene Mutations Quiz

What is a point mutation in the context of genetic mutations?

• A mutation affecting a large segment of DNA

• A mutation that occurs only in non-coding regions of DNA

• A mutation that involves a change in a single nucleotide base pair

• A mutation that results in the duplication of a whole gene

Which type of mutation involves the insertion of one or more nucleotide pairs into a DNA sequence?

• Deletion

• Insertion

What is a frameshift mutation?

• A mutation that does not change the amino acid sequence

• A mutation that changes only one base pair

• A mutation that results in the insertion or deletion of nucleotides that is not a multiple of three
