Transcription goes right-to-left through ORF B (because the Crick strand is the coding strand) so, the RNA transcripts will be smallest at the right (where transcription has just begun) and longest at the left (where it is about to end). For ORF C/D (Watson strand is coding) the situation reversed. ...
