What type of mutation will code for an amino acid but not the correct or desired amino acid?
- A. Insertion mutation
- B. Missense mutation
- C. Nonsense mutation
- D. Deletion mutation
Correct Answer: B. Missense mutation
Explanation
By definition, a missense mutation will still code for an amino acid, but not the desired amino acid. Silent mutations will have a different base pair, but due to the redundancy of genetic code, it will still code for the desired mutation. Nonsense mutations code for an amino acid that leads to a stop codon, which terminates the translation of mRNA into protein. Insertions and deletions result in a shifted reading frame and typically are detrimental.
