Abstract excerpt
RNA processing is an essential pathway in the regulation of genetic expression in the cell. In this work, Bacillus subtilis was used to understand the effects of mercury on the mechanism of tRNA metabolism. The CVAAS (cold vapor atomic absorption spectroscopy) method revealed that from the addition of HgCl2 (0.75 μg ml(-1)) during the bacterial exponential phase, ca. 48% of the added mercury was taken up by the...
