Cleavage map of bacteriophage T4 cytosine-containing DNA by sequence-specific endonucleases SalI and KpnI.
Cytosine-containing T4 DNA from endoII- endoIV- dCTPase- alc2 phage grown in a sup+ rB- mB- host is cleaved by endo R.EcoRI and endo R.HindIII to greater than 40 fragments and by endo R.SalI and endo R.KpnI to 8 and 6 fragments, respectively. The latter two fragment sets have been correlated to each other to produce a cleavage map of the genome. The sum of the molecular weights of the fragments calculated from electrophoretic mobility in agarose gels yields a genome molecular weight for cytosine-containing T4 DNA of 105 x 10(6).
