Percent of total transcription that is rRNA polymerized by RNA pol I

Range	~60 %
Organism	Budding yeast Saccharomyces cerevisiae

Primary Source	Woolford, J. L., Jr and Warner, J. R. (1991) in The Molecular and Cellular Biology of the Yeast Saccharomyces: Genome Dynamics, Protein Synthesis, and Energetics (Broach, J. R., Pringle, J. R. and Jones, E. W., eds), pp. 587–626, Cold Spring Harbor Laboratory Press
Method	As estimated from the synthesis of PolyA- RNA, as well as from calculations based on RNA abundance and stability, the transcription of rRNA by RNA polymerase I (Pol I) appears to represent nearly 60% of the total transcription in the cell (primary source)
