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.
Yes, it already has by changing the amino acid you have a mutation. That one amino acid counld be in the active site of an enzyme and that one amino acid being changed could result in loss of function or reduction in function of the enzyme. Sickle cell animea is caused by a single such amino acid substiution.
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.
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.

A silent mutation, where a nucleotide substitution results in a codon that codes for the same amino acid, would not change the remainder of the reading frame of a gene sequence. This is because the amino acid sequence produced by the altered codon remains the same.
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

The RNA sequence CUA codes for the amino acid leucine.
A mutation can change a codon for one amino acid into a different codon for the same amino acid through a process called silent mutation. This type of mutation occurs when a change in the DNA sequence does not alter the amino acid that is coded for, resulting in the same protein being produced.
