Just faintly remember reading about codon during my school days. I too read about this news and really frightening to visualise it’s consequences. Just reproducing the detail about what codon is for those interested. A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. Each codon corresponds to a single amino acid and the full set of codons is called the genetic code. It certainly doesn’t make any sense to me, though.
