Bacteriophage T7 DNA is isolated from an infected E.coli strain. The linear DNA has a length of 39936 bp, the complete sequence has been determined: Dunn, J.J. and Studier, F.W. (1983), Complete nucleotide sequence of bacteriophage T7 DNA and the locations of T7 genetic elements, J. Mol. Biol. 166 (4), 477-535
Phage T7 DNA is the most popular “alternative” to Lambda DNA substrate for the restriction endonucleases. The complete nucleotide sequence has been determined.
