N'ihi na DNA nwere anọ nucleotides, ngụkọta ọnụ ọgụgụ nke kwere omume codons bụ 64; ya mere, e nwere ụfọdụ redundancy na mkpụrụ ndụ ihe nketa koodu, na ụfọdụ amino asịd kpọmkwem site ihe karịrị otu codon. Genes koodu na DNA na-mbụ transcribed n'ime biosensor RNA (mRNA) site na ndị dị ka RNA prokaryotes.
