how could u have your nuclease S1-digested hybrid DNA-mRNA converted in
dsDNA. You'll have several fragments (introns + 1) not ligated. And if you
want to amplify yaour fragments you'll have to design and use two primers
for each exon you want to be amplified. If I'm wrong, tell me so I'll
increase my knowledge in PCR technique.
