The chemical alkylating agent dimethyl sulfate can probe the interaction between Escherichia coli RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6) and the purine bases of a promoter. This agent methylates the N7 position

We performed a genetic and sequencing analysis of insertions of the transposon Tn9 into the lac operon of E. coli. Genetic mapping of 70 insertions into lacl and Z shows that starting from the same point on the chromosome, Tn9 goes to at least 50 dif

We have detected two independent occurrences of insertion mutations in the lacl gene of E. Coli, and have used small plasmids carrying the l gene to purify large amounts of DNA containing these insertions. Analyses with restriction endonucleases and

Publisher Summary This chapter discusses the use of DNA fragments of defined sequence for the study of DNA damage and repair. A wide variety of physical and chemical agents damages the DNA. The biological effects of such agents include cell death, ne

The defining characteristic of bacterial transposons is their ability to move to new loci in the absence of extensive DNA sequence homology. Some, designated IS elements, contain only the genes and sites necessary for their own transposition; other t

The nucleotide sequence of an IS1 element recently transposed into the lacI gene is reported. This sequence is nearly identical to one previously reported for another IS1 element (Ohtsubo and Ohtsubo, 1978). The implications of this similarity are di

Double-stranded cDNA prepared from the 12S fraction of poly(A) RNA from interferon (IF)-producing human leukocytes was cloned in Escherichia coli using the pBR322 vector. One of the resulting clones had a 910-base pair insert which could hybridise to
