||Primary source (13): "The novel isolation procedure consisted of simultaneous selection for rifampicin resistance and screening for increased leakiness of an early, strongly polar nonsense mutation of lacZ, one of a special class of mutations whose leakiness reflects mainly transcriptional rather than translational errors."

||P.1518 left column 2nd paragraph: "The transcription error-rate is about 0.5 to 1.0×10^-5 per nucleotide, according to
in vitro estimates [Primary source (13)] but may reach 5×10^-5 at some loci in vivo [Primary source (14)]. The reasoning will be in terms of a standard transcription error-rate of 10^-5." See BNID 103453 for misincorporation rate of 10^-4 in transcription. Value of 10^-5 also given by Ortego et al 2007 PMID 17985929.
