the presence of ribonucleotides on the 5 ' termini of molecules with both leading- and lagging-strand polarity was demonstrated by ( i ) release of 32p-ribonucleoside diphosphates upon alkaline hydrolysis of [ 5'-32p ] dna separated according to replication polarity and ( ii ) the change in the degree of self-annealing of nascent molecules upon preferential degradation of dna molecules possessing initiator rna moieties by spleen exonuclease .
