Salient features of genetics code -

1. The codon is triplet, 61 codons code for amino acids and 3 codons do not code for any amino acids, hence they function as stop codons.

- wherein

 

 

 

The codons for the various Amino acids.

 

 If one strand of DNA has the nitrogenous base sequence as ATCTG, the complementary sequence of mRNA will be UAGAC.
