Abstract

The mechanisms for generating transcript diversity have been studied experimentally, using various biochemical methods including variants of PCR, S1 nuclease assays and blot hybridizations. The conclusion about the mechanism(s) involved, can be reached after nucleotide sequencing and computational analysis. Hence, sentences describing events that generate TD (Supp figure 3) may contain event mechanisms, results of the experimental methods or statements describing observations or presumptions.
