the results suggest that the enzyme prefers partially doublestranded or hybrid regions of rnas for optimal dna synthesis , but certain regions of single-stranded rna can also serve as templates.poly ( dat ) competes with viral rna for purified dna polymerase during dna synthesis , as would be expected if rna- and dna-dependent dna synthesis was performed by at least one common active site of the same enzyme .
