Frequency of hTERT mRNA ASPSs in RT-PCR cDNA clones. The tissue of origin is indicated above the graph with number of analysed clones in brackets. Black bars show the percentage of clones containing the indicated ASPS. The fraction of these for which the 5'-splice donor site is continuous with the ORF (not masked by other ASPSs further upstream that terminate the ORF) is shown by an adjacent cross-hatched bar.
