Abstract excerpt

The extrachromosomal element psi affects translation fidelity in the yeast Saccharomyces cerevisiae by increasing the efficiency of tRNA-mediated ochre suppression. The nature of the psi factor is unknown, although there is evidence that 3-microns circles from psi+ strains can be used to transfor...
