As well DNAse treating the RNA, its important to do a control PCR
reaction using mock-reverse transcribed RNA as a template (do this by
adding everything to the RNA except reverse transcriptase).  That way you
will be absolutely sure you have no DNA contamination.  For a good
reference about this, see the SRY1 cloning paper (Goodfellow, I think).
