The mRNA/+RNA description: 
Bicistronic mRNA transcribed in vitro using T7 polymerase while transcription was supposedly terminated
immediately after the Tphi termination signal sequence. The CAT-fusion ORF sequence contains at its 5'-end
additional 28nt (including ATG) from HCV polyprotein followed by mutated sequence followed then by KpnI site,
followed by hairpin structure, followed then by the CAT sequence itself (including the so called ACAT sequence
(CGAGAAAAAAATCAC)).
