The quality of the mRNA/+RNA sequence:
  hopefully_full-length_mRNA
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 14nt (including ATG) from HCV polyprotein followed by KpnI site, followed then by the so called
ACAT sequence (CGAGAAAAAAATCAC) and the CAT sequence itself.
