Feature of the genetic code

WebFirst of all - let's be clear: the genetic code is the set of rules from which DNA is converted in functional units (either protein or non-coding RNA). For making proteins, sets of three nucleotide bases (codons) will code for a specific amino acid. WebVerified by Toppr The salient feature of genetic code are as follows: (i) The codon is a triplet. 61 codons code for 20 amino acids and 3 codons do not code for any amino acids, hence they function as stop codons. (ii) One codon codes for only one amino acid, hence, it is unambiguous and specific.
