Bacteriophage Mu DNA circularizes following infection of Escherichia coli.

DNA injection during bacteriophage T4 infection of Escherichia coli.

The process of phage T4 DNA injection into the host cell was studied under a fluorescent microscope, using 4',6-diamidino-2-phenylindole as a DNA-specific fluorochrome. The phage DNA injection was observed when spheroplasts were infected with the artificially contracted phage particles having a protruding core. The DNA injection was mediated by the interaction of the core tip with the cytoplasm...

Characterization of leucine transfer ribonucleic acid in Escherichia coli following infection with bacteriophage T2.

Reversed phase column chromatography was used to fractionate leucine transfer RNA from Escherichia coZi, both from uninfected cells and from cells 8 min after infection with bacteriophage T2. Each type of tRNA gave five components of leucine tRNA, leul to leus. Comparison of the two chromatographic proliles indicated that the relative amount of leul decreased after T2 infection, with a correspo...

Streptomycin and infection of Escherichia coli by T6r+ bacteriophage.

Freda, Celia E. (University of Pennsylvania School of Medicine, Philadelphia), and Seymour S. Cohen. Streptomycin and infection of Escherichia coli by T6r(+) bacteriophage. J. Bacteriol. 92:1670-1679. 1966.-The thymineless, histidineless, uracil-less Escherichia coli 15 THU was shown to be sensitive to streptomycin, dying in patterns comparable to that of strain 15 TAU in the presence or absenc...

In vivo production of an RNA-DNA copolymer after infection of Escherichia coli by bacteriophage T4.

An RNA-DNA copolymer was isolated from Escherichia coli infected with bacteriophage T4. The RNA and DNA are covalently linked, and in the same polynucleotide strand. The DNA of the copolymer hybridizes specifically to the left strand of phage T4 DNA. The copolymer is produced in cells infected with amber mutants of phage T4 deficient in DNA replication and is not inhibited by the addition of ch...
