Alternative splicing takes place in more than 95% of the human protein-encoding genes with multiple exons. Researchers have found that how a pre-mRNA is spliced is affected by the pre-mRNA’s promoter sequence (D. Auboeuf et al. 2002. Science 298:416–419). In addition, factors that affect the rate of elongation by the RNA polymerase during transcription affect the type of splicing that takes place. These findings suggest that the process of transcription affects splicing. Propose one or more mechanisms that would explain how transcription might affect alternative splicing.
