we have recently developed an in vitro dna synthesis system in which a synthetic heptaribonucleotide pairs with a unique site on a single-stranded fd dna molecule and thereby primes the growth of new dna strands from this single point ( huang , c.-c. , and hearst , j. e. ( 1980 ) anal . biochem . 103 , 127-139 ) .
