Mutation - NIU Department of Biological Sciences
... Mutations can be classified according to their effects on the protein (or mRNA) produced by the gene that is mutated. 1. Silent mutations (synonymous mutations). Since the genetic code is degenerate, several codons produce the same amino acid. Especially, third base changes often have no effect on t ...
