DNA Mutations

Front

If a mutation occurs that does not change the amino acid, it is called a ___________ mutation.

Back

silent mutation

Front

Normal DNA sequence: GAG-CTC-GAC-AGA. Mutant sequence: GAG-CTC-CAC-AGA. What type of mutation occurred?

Back

substitution

Front

DNA molecule segment is: TTA-CGC-AAG. The mutated DNA segment is TTC-GCA-AG. This is an example of ___ mutation.

Back

Deletion

Front

In DNA, A goes with __ and C goes with __.

Back

A goes with T and C goes with G.

Front

If you are missing or have an extra base at the end of your mutated DNA, what type of mutation occurred?

Back

Frameshift

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is a missense mutation?

Back

A missense mutation is a type of mutation that results in a different amino acid being incorporated into a protein.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a mutation that creates a premature stop codon in the DNA sequence, leading to a truncated protein.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is the role of DNA polymerase in mutations?

Back

DNA polymerase is the enzyme responsible for replicating DNA, and errors during this process can lead to mutations.
