Chimeric RNAs are the transcripts composed of exons from two separate genes or transcripts. Although the presence of these joined RNA molecules have mainly been documented in a variety of eukaryotes, we recently demonstrated that the Ll.LtrB group II intron, from the gram-positive bacterium Lactococcus lactis, can generate chimeric mRNAs through a novel intergenic trans-splicing pathway. Here we describe the detailed experimental procedures to detect group II intron-generated mRNA–mRNA chimeras from total RNA extracts using stringent reverse transcription conditions along with a reverse splicing-deficient group II intron as a negative control.
