The HCV genome contains a single, long, open reading frame (3,006-3037 codons) flanked by 5' and 3' untranslated regions (UTRs). The HCV RNA genome is used both for translation and transcription. WebThe older classic concept of the basic hepatic histologic structure is that of the hepatic lobule ( Fig. 5-2 ). This model is that of a polygon, typically a hexagon, with branches of the portal triad (hepatic artery, portal vein, and bile duct) at the vertices.
