the nucleotide sequence of the sv40 genome region between the hind k fragment and the eco ri cleavage site has been determined by a combination of three different approaches : analysis of rna products obtained by transcription with escherichia coli dna dependent rna polymerase , partial degradations with snake venom exonuclease and base-specific chemical degradation of 5'-terminal labeled restriction fragments .
