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.
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
a silent mutation.
A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.
mutation is a permanent change in the DNA sequence of a gene and can alter the amino acid sequence of the protein encoded by the gene..

It is neutral mutation. Codons are made up of 3 base pairs. This gives 64 different combinations, but there are only 20 amino acids, so some different codons will code for the same amino acid. When the base pair that is changed doesn't cause a change in the amino acid it codes for, then ultimately nothing happens
A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.

If the mutant codon still codes for the same amino acid (a silent mutation). For example: GUU, GUC, GUA and GUG all code for the amino acid Valine. So if the mutation changed the codon from GUU to GUA - Valine would still be produced and therefore the polypeptide will be identical.
