replication with escherichia coli dna polymerase i ( pol i ) and transcription with dna-dependent rna polymerase from escherichia coli or calf thymus , using as templates synthesized ribo- or deoxyribopolynucleotides containing 1 , n6-ethenoadenine ( epsilon a ) or 3 , n4-ethenocytosine ( epsilon c ) , showed that only epsilon c could direct significant misincorporation .
