From: Reverse complementary matches simultaneously promote both back-splicing and exon-skipping
RCMs do not promote exon-skipping through back-splicing, neither the other way. a Gene structure of zip-2. P1-P6: positions of primers. Positions of splicing sites and branch points that are required for back-splicing and exon-skipping are labeled. Positions of RCMs are in red. b Cropped gel image showing RT-PCR detection of zip-2 transcripts in wild-type N2 strain and strains with mutated ss or BP. Note the cryptic splicing in circ-3’ss strain
