electron microscope measurements of the linear ecori-treated replicative intermediates indicate that replication can be initiated at two sites ( origins ) on the plasmid dna molecule located at about 23 % ( alpha ) and 39 % ( beta ) of the total genome length from an ecori end designated arbitrarily as the `` '' left-hand '' '' end of the molecule .
