UGA stands for Threonine. UGG stands for Threonine. Nothing would change. This is none as a silent mutation.

^ actually, according to my chart, UGA is a stop codon and UGG stands for TRYPTOPHAN (not threonine), also UGG is the ONLY codon that codes for tryptophan, so it isn't a silent mutation, either. the correct answer is that the peptide will be longer than normal.

ReneChanging the codon UGA to UGG would result in a different amino acid being incorporated into the protein during translation. UGA normally functions as a stop codon, signaling the end of protein synthesis. However, UGG codes for the amino acid tryptophan, so the change could lead to the addition of tryptophan in the protein sequence instead of terminating translation.

Are amino acid that are represented by one codon?
Yes, there are two amino acids that are represented by a single codon. Methionine is coded for by the start codon AUG, and tryptophan is coded for by the codon UGG.
What do codons UGG and AUG have in common?
Both codons UGG and AUG are start codons that initiate the process of translation in protein synthesis. AUG codes for the amino acid methionine, which is typically the first amino acid in a protein sequence. UGG codes for the amino acid tryptophan.

Which amino acid was never coded for?
Several amino acids are not coded for in biology. 20 are. The two standard amino acids are selenocysteine and pyrrolysine. Then there are the numerous non-standard amino acids, which include hydroxyproline and selenomethionine.
Why does mrna mutation affect the amino acid sequence?
The codon UGU codes for the amino acid Cysteine. The codon UGG codes for the amino acid Tryptophan. Therefore the mutation will cause the amino acid Cysteine to be replaced with Tryptophan. These amino acids are quite different, and the final shape of the protein could be changed as a result. This could affect the function of the protein.
