Three Rules Govern The Genetic Code

The genetic code is subject to three rules that govern the arrangement and use of codons in messenger RNA. The first rule holds that codons are read in a 5' to 3' direction. Thus, in principle and as an example, the coding sequence for the dipeptide N LL -Th r- Arg-GOOH could be written as 5-ACGCGA-3' (where 5'-AGG-3' is a threonine codon and 5J-CGA-3' an arginine codon] or as 3'-GCAAGC-5' wherein the codons are written in the same order as before but oppositely to their original
