Unambiguous, universal and degenerate are some of the terms used for the genetic code. Explain the salient features of each one of them.
Unambiguous : one codon codes for only one amino acid.
Degenrate : Some amino acid are coded by more then one coden.
Universal : Is coded by the same codon in all living organisms.
For example from bacteria for human beings UUU codes for phenylalanine (phc) the same aminio acid.
