Unambiguous’, ‘degenerate’ and ‘universal’ are some of the salient features of genetic code. Explain.
Unambiguous: Each codon codes for one amino acid, none for more than one. Degenerate: One amino acid often has more than one triplet codon; only methionine and tryptophan have a single triplet codon. Universal: The genetic code is universal. A given codon in DNA and m RNA specifies the same amino acid in all organisms from viruses, bacteria to human beings.
