The statement is correct. Because of
degeneracy of codons, mutations at third base of codon, usually does not result
into any change is phenotype. This is called silent mutations.
On other hand, if codon is changed in
away that now it specifies another amino acid, it may other the protein
function as it happens in case ofb-globulin
of hemoglobin protein. Where a substitution of valine instead of glutamic acid
causes change in its structure and function and resulting into sickle-cell
