A mutation may or may not affect the amino acid sequence. A mutation may or may not affect the phenotype. Some specific mutations in a gene may have more adverse affects than other mutations in the same gene. A mutation is not necessarily bad. It may even be good. A mutation may enhance or positively change the function of the protein produced by the gene.
Mutations are random changes in DNA. Most DNA does not actually come into play in building the organism's body so mutations in that DNA are neither helpful nor harmful. Mutations in the DNA that is used to build the organism's body are mostly harmful.utation is a change in the encoded hereditary information in living things and viruses. Whether or not it's good or bad depends on what the effects of it are. And even that is relative. Example: A plant grows with a new mutation, the ability to produce a more powerful toxin in it's seed pods.
