Identify giving reasons, the salient features of genetic code by studying the following nucleotide sequences of mRNA strand and the polypeptide translated from it? 

Answer»

Prosperities of genetic code:

- AUG is the initiation codon and codes for methionine; methionine is the first amino acid in the given polypeptide. 

- Genetic code is unambiguous and specific, i.e., each codon codes only for on particular amino acid. 

- Genetic code is degenerate, i.e., more than one codon code on one amino acid. 

- Each codon is a triplet, i.e., made of three nucleotides e.g., AUG, UUU, etc. 

- UAG does not code for any amino acid, it is a termination codon.
