MicroRNA synthesized by rolling circle transcription (RCT) site-specific disconnection (SSD) with various concentrations of circular cDNA template. (a) Time course of RCT in the absence of inorganic pyrophosphatase (IPP). (b) Effect of IPP on the amount of RNA products. Lane L, 25 nt RNA marker; Lane S, standard sample of chemically synthesized mir-16 (1 μl, 100 μmol/l). In (b), RCT was processed for 4 hours, with 0.1 μmol/l Aid-DNA-16-1 and 1.0 U/ml IPP.
