Using an RNase H - mediated mapping technique , we show that the 64 - kDa subunit of CstF can be photo cross - linked to pre - mRNAs at U - rich regions located downstream of the cleavage site of the simian virus 40 late and adenovirus L3 pre - mRNAs .
 GENE: RNase H; GENE: CstF; GENE: adenovirus L3 pre - mRNAs
