the term is called Mutation. What happens is that either you will have a product which is non-functioning, too small, or digested by the cell proteosomes as soon as produced because of the error. It all depends on the mutation suffered by the DNA. RNA has many mutations which are not corrected by the cell due to its short life and the fact that Translation can still continue correctly if the first two amino acids are correct. Otherwise, if the first two are affected, such as in frame shift mutation, or one or two amino acid deletions, then wrong base will be added, which can lead to problems stated above.
