The nucleotide sequence preceding an RNA polymerase initiation site on SV40 DNA. Part 1. The sequence of the late strand transcript.

The nucleotide sequence of the transcript of the "late" strand of the region of SV40 DNA preceding the preferred initiation site for Escherichia coli RNA polymerase has been determined to be U-G-U-A-A-C-C-A-U-U-A-U-A-A-G-C-U-G-C-A-A-U-A-A-A-C-A-A-G-U-U-A-A-C-A-A-C-A-A-C-A-A-U-U-G-Cp. Hemophilus influenza restriction endonuclease cleaves this region 30 nucleotides (base pairs) before the site of initiation of RNA synthesis by RNA polymerase.
