In vitro and in vivo transcription initiation sites on the TK-encoding BamHI Q fragment of HSV-1 DNA.
The sites of in vitro transcription initiation on the BamHI Q fragment of herpes simplex virus DNA have been compared with the sites of 5' ends of RNAs made in vivo after virus infection. S1-nuclease protection analysis of these RNAs shows that there are in vivo counterparts for each of the five previously identified in vitro transcripts. The whole-cell-extract RNA polymerase II transcription system faithfully initiates RNAs predominantly at bona fide in vivo start sites and gives few, if any, false positive start sites. Further, antiparallel, self-complementary transcripts from the BamHI Q fragment were observed in the coding region of the HSV thymidine kinase gene.
