Unambigous, universal and degenerate are some of the terms used for the genetic code. Explain the salient features of each one of them

Umnambiguous - One codon codes for one amino acid = e.g.AUG
Universal - Codon and its corresponding amino acid are the same in all organisms.
Example : Bacteria to human UUU codes for phenylalanine.
Degenerate - Some amino acids are coded by more than one codon.
Example : UUU and UUC code for phenylalanine.
