RESUMO

The nucleotide sequence of the RNA transcript from the “early” (E) strand of SV40 DNA immediately preceding the preferred E. coli RNA polymerase start site is G-(A-A-A-C, -A-U-)-A-A-A-A-U-G-A-A-U-G-C-A-A-U-U-G-U-U-G-U-U-G-U-U-A-A-C-U-U-G-U-U-U-A-U-U-G-C-A-G-C-U-U-A-U-A-A-U-G-G-U-U-A-C-Ap. The last nucleotide of the sequence is the first nucleotide transcribed by E. coli RNA polymerase from the “E” strand. The DNA template contains a palindrome of 17 residues that includes the Hemophilus influenza restriction endonuclease cleavage site G-T-T-A-A-Cp. The DNA which gives this transcript lies very close to one end of SV40 DNA segment in the Adeno-SV40 hybrid virus Ad2+ND3 and appears to contain sufficient untranscribed information to specify the E. coli RNA polymerase start.
