  1. DNA sequences retrieved from the National Center for Biotechnology Information database. The symbol _ and the underlined bases represent the end and the beginning of the GP5+ PCR priming site, respectively. A 34-base sequence shared by HPV-16 and certain HPV-31 (EF140820) and HPV-33 (DQ448214) strains is located immediately downstream of the GP5+ site. A 1- to 4-base difference is present upstream of the GP5+ site between certain variants of HPV-16, HPV-31 (EU779751) and HPV-33 (EU779744).
