Conditional Lethality of recA and recB Derivatives of a Strain of Escherichia coli K-12 with a Temperature-Sensitive Deoxyribonucleic Acid Polymerase I
We have isolated a strain of Escherichia coli K-12 carrying a mutation, polA12, that results in the synthesis of a temperature-sensitive deoxyribonucleic acid (DNA) polymerase I. The double mutants polA12 recA56 and polA12 recB21, constructed at 30 C, are inviable at 42 C. About 90% of the cells of...
