Nucleotide sequences of RNA transcribed in infected cells and by Escherichia coli RNA polymerase from a segment of simian virus 40 DNA.

The nucleotide sequence of 180 residues of an RNA transcript of DNA of simian virus 40 has been deduced. This sequence adjoins a preferred initiation site for E. coli RNA polymerase. Comparison of this sequence with that of complementary RNA of simian virus 40 from infected cells has shown that this site also adjoins the apparent 3' terminus of some of the cytoplasmic complementary RNA of simian virus 40.

The mapping and ordering of fragments of SV40 DNA produced by restriction endonucleases.

SV40 DNA is cleaved by the Eco RII and Hae restriction endonucleases to give rise to two different sets of 16 fragments each. These fragments have been ordered by analysis of the products of redigestion of one set of fragments with another restriction enzyme. The cleavage sites have been precisely mapped based on length measurements of the products of each cleavage. This provides a convenient group of small DNA fragments suitable for sequence analysis investigation of the transcripts present in infected cells, or construction of deletion substitution variants of the virus.
