The E. coli rrn promoters are also regulated by a pair of small molecules: the initiating NTP (the iNTP) and an alarmone,  guanosine 5 -diphosphate 3-diphosphate (ppGpp). An abundance of iNTP indicates that the concentration of  nucleotides is high, and therefore it is appropriate to synthesize plenty of rRNA.

Readthrough transcripts refer to the fraction of transcripts that are not stopped by the terminator. (Readthrough is the same term used in translation to describe a ribosome’s suppression of termination codons.)
