||Primary source abstract:"The fidelity of yeast RNA polymerase II (Pol II) was assessed in vivo with an assay in which errors in transcription of can1–100, a nonsense allele of CAN1, result in enhanced sensitivity to the toxic arginine analog canavanine."
||"In eukaryotic transcription, Nesser et al. previously
analyzed transcription errors throughout ~450-bp
cDNA of CAN1 transcript in yeast by Sanger sequencing
(primary source). Their work reported a much higher 1.3×10^-3/bp rate
of substitutions compared to the rate observed for E. coli
RNAP in [researchers'] study and the rates determined for yeast
RNAP II in vitro (Kireeva et al. 2008 PMID 18538654)."
