Correlation between genetic map and map of cleavage sites for sequence-specific endonucleases SalI, KpnI, BglI, and BamHI in bacteriophage T4 cytosine-containing DNA.

Cleavage sites for SalI, KpnI, BglI, and BamHI in cytosine-containing DNA from T4 alc10(alc) nd28(denA) D2a2(denB) amE51x5(56) amN55x5(42) have been mapped relative to each other, and the positions of deletions sa delta 9 (D1-stp), r1589(rII), del(39-56)12, and tk2(rI-tk) relative to these cleavage sites have been determined. Based on these analyses, a physical map of the T4 genome containing 166 kilobase pairs has been constructed.
