Question
A mutation changes a TCA codon to TCG. Please choose the best classification for this mutation.Silent mutationFrameshift mutationNonsense mutationMissense mutation
Solution 1
This is a Silent mutation. The reason is that both TCA and TCG codons code for the same amino acid, Serine. Therefore, even though the DNA sequence has changed, the resulting protein will not be altered. This type of mutation is called a silent mutation.
Solution 2
This is a Silent mutation. The reason is that both TCA and TCG codons code for the same amino acid, Serine. Therefore, even though the DNA sequence has changed, the resulting protein will not be altered.
Solution 3
This is a Silent mutation. In this case, both TCA and TCG codons code for the same amino acid, Serine. Therefore, even though the DNA sequence has changed, the resulting protein sequence does not, hence it's called a "silent" mutation.
