Abstract

The gene sup61+, which codes for the essential Saccharomyces cerevisiae tRNA(SerUCG), is the only single-copy tRNA gene in this organism know to contain an intron. To assess the role of this intron in tRNA gene expression, an intron-deleted sup61+ gene was constructed in vitro and introduced into the yeast genome. Isogenic intron- and intron+ strains were found to be indistinguishable by criteria that include growth rates, ability to undergo meiosis, levels of mature tRNA(SerUCG) transcribed in vivo, and the suppressor efficiency of amber- and ochre-specific alleles of this gene.
