Fig. 14. cDNA sequence of the 5' ends of a sample of troponin T (TnT) transcripts that do not contain alternative exon 5. cDNA was amplified from three individuals from Ten Acre Pond (TenA.148, TenA.133 and TenA.156) and two from Mothersbaugh Pond (MbB.11 and Mb.16) using primers against the 5' untranslated region and constitutive exon 8. Products from polymerase chain reactions were subcloned and sequenced. The bar at the top of the plot shows the exon structure, below which is the consensus sequence. Only the coding region through a portion of exon 7 is shown here.
