Supplementary Figure 30. Analysis of the ccmC t-element. A modified CR-RT-PCR using endogenous 18S rRNA as adapter molecule was carried out to determine the 5’ end (B-D) and the 3’ end (E-G) of the t-element downstream of the ccmC transcript (A). The site of the endonucleolytic cleavage of the pre-mRNA is marked by a pair of scissors. Primers indicated in tables (C) and (F), respectively, were used and the PCR products were separated by agarose gel electrophoresis (B and E). The products (marked by an arrow) were excised and analyzed by sequencing. The ends identified within the PCR products are given in tables (D) and (G), respectively.
