SL2 RNA is a
non-coding RNA involved in
trans splicing in lower eukaryotes. Trans-splicing is a form of RNA processing. The acquisition of a spliced leader from an SL RNA is an inter-molecular reaction which precisely joins
exon
An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term ''exon'' refers to both the DNA sequence within a gene and to the corresponding sequen ...

C. elegans
''Caenorhabditis elegans'' () is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek ''caeno-'' (recent), ''rhabditis'' ( ...
'' genes are organised into
polycistronic transcription units and the presence of SL2 on an mRNA is an indication the gene is in an
operon.
