Circular DNA behaves as an efficient template for RNA polymerase (RNAP) in rolling circle transcription (RCT). We found that the short hairpin-stem structure in the circular DNA without promoter enhances the DNA recognition of T7 RNAP in RCT. The result indicates that T7 RNAP would distinguish the short DNA hairpin-stem structure.
