passages.text: To investigate the functions of GE , IG , and GS sequences in transcription , we constructed plasmids containing cDNAs of the full - length SV5 genome in which the gene junction sequences ( GE , IG , and GS sequences ) located between the hemagglutinin - neuraminidase ( HN ) and the polymerase ( L ) genes were replaced with the counterpart sequences from other gene junctions .
