The effects of daunomycin and ethidium bromide on Escherichia coli

Molecular and General Genetics MGG, 1973
The effects of two DNA-intercalating agents daunomycin (DMC) and ethidium bromide (EBR) on transcription, translation and replication in Escherichia coli have been studied. The data are consistent with the notion that low concentrations of these drugs primarily inhibit transcription and replication to equal extents and that translation is halted ...

Ethidium Bromide Interaction with Poly(G)

Biophysical Reviews and Letters, 2014
In current work we investigate the interaction between polyguanylic acid and Ethidium Bromide ( EtBr ) and the changes of thermodynamic parameters due to those interactions by spectrophotometric methods. From the binding isotherms, binding constants were calculated for three different temperatures and the changes of Gibbs free energy, entropy and ...

Resistance to ethidium bromide inAspergillus nidulans

Experientia, 1979
A mutant ofAspergillus nidulans resistant to ethidium bromide was isolated and the semi-dominant gene responsible for this resistance was allocated on linkage group II at 17.42±3.05 units of recombination from thewA3 gene. The gene also confers cross-resistance to acriflavin, malachite green and crystal violet.

Ethidium bromide resistance and enhancement of mitochondrial recombination

Molecular and General Genetics MGG, 1974
In some yeast cytoplasmic mutants, ethidium bromide resistance is expressed at the mitochondrial level. In homosexual crosses it leads to an enhanced recombination between two linked mitochondrial genes controlling chloramphenicol and erythromycin resistance or sensitivity, but recombination is still reciprocal.

Mechanism of ethidium bromide inhibition of RNA polymerase

Journal of Molecular Biology, 1973
Abstract The effect of ethidium bromide on various steps of the reaction catalyzed by Escherichia coli DNA-dependent RNA polymerase is studied. Inhibition caused by low levels (approx. 6 μm) of this DNA-binding drug is a consequence of reducing the rate of RNA chain initiation; the rate of RNA chain growth is unaffected at this concentration.

Neurotoxic Effects of Ethidium Bromide, Rat

1988
Pathologic lesions are produced by a direct exposure of the central and peripheral nervous tissues to ethidium bromide which is a red dye. Therefore the lesion appears red or reddish-orange and softer than the surrounding tissue.
