Priming DNA Replication from Triple Helix Oligonucleotides: Possible Threestranded DNA in DNA Polymerases

Figure 3

Results of elongation by several DNA polymerases with various templates/primers. Additional templates in an antiparallel orientation (i.e., 3′->5′ instead of 5′->3′) and presenting 3 A/A mismatches were nonproductive as well as 5′d(GGATTACGAG)3′ in a parallel and an antiparallel orientation.
