uracil: failure to restore dna synthesis while relieving 5-fluorouracil-induced inhibition.growth inhibition of bacillus cereus by 5-fluorouracil is abolished by the addition of uracil without the inhibition of dna synthesis being relieved. the growth rate, protein, and rna content of cells grown in the presence of 5-fluorouracil and uracil are unaffected until the cells contain only about 25 percent of their normal dna content.196414171570
tetracycline fluorescence in permeability studies of membranes around intracellular parasites.certain protozoa, bacteria, and viruses when phagocytosed by host cells become surrounded by an intracytoplasmic boundary. this membrane prevents the fluorescent antibiotic tetracycline from entering the parasites when it is added to the medium, since they show no fluorescence, whereas extracellular parasites are immediately visible. as soon as the host cell dies, the intracellular parasites also become visible. this indicates that the boundary probably is of host origin. this phenomenon provide ...196414171865
