||Primary source abstract: "Genome-wide expression analysis was used to identify genes whose expression depends on the functions of key components of the transcription initiation machinery in yeast."
||P.1263 left column bottom paragraph: "High-throughput analyses in yeast
showed that protein variation for most genes is low [ref 11]. However, in
the yeast Saccharomyces cerevisiae, most mRNAs are present in low
abundance: 80% of the transcriptome, including many essential genes,
are expressed at less than two copies per cell [primary source]."
