Abstract
The complete nucleotide sequences of the human papillomavirus type 16 (HPV-16) variants present in the CaSki and SiHa cervical carcinoma cell lines and the primary subgenomic HPV-18 variant present in the HeLa cervical carcinoma cell line were determined using overlapping bulk PCR products as templates. PCR-based methods were also used to characterize five previously unreported CaSki HPV-16 genomic disruptions and the 5' cellular--viral junction common to all HeLa HPV-18 subgenomic structures.
