  • Title: Characterization and physical map of choleraphage phi 149 DNA.
    Author: Sengupta A, Ray P, Das J.
    Journal: Virology; 1985 Jan 30; 140(2):217-29. PubMed ID: 2982231.
    Abstract:
    Choleraphage phi 149 DNA is a linear double-stranded molecule 69 X 10(6) Da or 104 kilobase pairs (kbp). From restriction enzyme analysis, it has been concluded that the DNA is circularly permuted. There are at least three S1 nuclease-sensitive sites along the length of the molecule. These sites represent single-strand interruptions repairable by T4 DNA ligase. A physical map of the DNA has been constructed using the restriction endonucleases BamH1 and BglII.
