title: Nucleotide pools and regulation of ribonucleic acid synthesis in yeast.
abstract: Nucleotide pools were measured in growing and amino acid-starved Saccharomyces cerevisiae. During amino acid starvation there are neither significant changes in the endogeneous nucleoside triphosphate pool levels nor measurable synthesis of guanosine 5'-diphosphate, 3'-diphosphate. Stable ribonucleic acid synthesis does not appear to be regulated by changes in the triphosphate pools or by the unusual nucleotide guanosine 5'-diphosphate, 3'-diphosphate.
