What is degeneracy in the genetic code and how does influence the effects of certain mutation?
Degeneracy of the Genetic code means that several codons code for a certain amino acid except for methionine and tryptophan. This minimizes the effect of mutation. this is usually called the Wobble theory since some codons can accomodate any base in the third position but still coding the same amino acid.
Reply:The degeneracy in the genetic code means that there are several things that codes for the same things (but the same sequence cannot code for different things). Different codons (three base pairs coding for one amino acid) code for the same amino acid, for example both GAA and GAG codes for glutamic acid for example. This mean that certain mutations does not change anything at all. Like, if the last A in the GAG codon would mutate into a G, the codon would still code for glutamic acid, so no actual change on a protein level could ever be observed (the mutation would not actually do anything).
