WebDNA sequences are determined by exploiting the enzymatic characteristics of DNA polymerase. DNA polymerases all require a primer to initiate synthesis. The sequencing reaction begins when a single primer is hybridized to the strand of DNA to be sequenced. This primer‐initiated synthesis is just like the initiation of a PCR. WebDNA is only synthesized in the 5' to 3' direction. You can determine the sequence of a complementary strand if you are given the sequence of the template strand.
