Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated. For example, if the codon AAA is altered to become AAG, the same amino acid – lysine – will be incorporated into the peptide chain.
Consequently, what is the difference between nonsense and missense mutation?
A base substitution may have three different effects on an organism's protein. It can cause a missense mutation, which switches one amino acid in the chain for another. It can cause a nonsense mutation, which results in a shorter chain because of an early stop codon.
What is a missense mutation?
In genetics, a missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid. It is a type of nonsynonymous substitution.
What are the 4 types of DNA mutations?
The types of mutations include: Missense mutation. This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. Nonsense mutation.
