Question
What does a non-sense mutation do?
- Change one amino acid to a stop codon
- Change one amino acid to a different amino acid
- Change one amino acid to a start codon
. - None of the above
Hint:
A nonsense mutation is a change in DNA that causes a protein to terminate
The correct answer is: Change one amino acid to a stop codon
- A nonsense mutation, or its synonym, a stop mutation, is a change in DNA that causes a protein to terminate or end its translation earlier than expected
- A genetic alteration that causes the premature termination of a protein.
- The altered protein may be partially or completely inactivated, resulting in a change or loss of protein function.
