Give scientific reasons: Unambiguous,universal,and degenerate are some of the terms used for the genetic code.

(N/A) Unambiguous code means that one codon codes for only one amino acid; for example,$AUG$ codes only for methionine.
Genetic code is universal,meaning a particular codon codes for the same amino acid in all organisms.
It is degenerate because some amino acids are coded by more than one codon; for example,$UUU$ and $UUC$ both code for phenylalanine.
