Mammalian gene expression is inherently stochastic1,2 , and results in discrete bursts of RNA molecules that are synthesized from each allele3-7 . Although transcription is known to be regulated by promoters and enhancers, it is unclear how cis-regulatory sequences encode transcriptional burst kinetics. Characterization of transcriptional bursting, including the burst size and frequency, has mainly relied on live-cell4,6,8 or single-molecule RNA fluorescence in situ hybridization3,5,8,9 recordings of selected loci...
