,South Africa’s Salvation: The War over Gold, a vague but pervasive belief that some simple mineral, merely raised out of the soil of the happy country in which it lies, should not be allowed to ‘count’. Count, that is, in terms of international trade against such works of human ingenuity and labour as cars, televisions and jet planes. But, of course, count it does.

d as the enzyme that mediates cleavage of precursor tRNAs at the 5′-end termini to generate the mature tRNAs. An important characteristic of RNase P is that its specificity depends on the structure rather than the sequence of the RNA substrate. Any RNA species that interacts with an antisense molecu

R. W. Johnsonity, and biofilm formation in diverse bacterial species. The activity of CsrA/RsmA is regulated by small RNAs that contain multiple binding sites for the protein. The expression of these noncoding RNAs effectively sequesters the protein and reduces free cellular levels of CsrA/RsmA. While multiple b
