Figure 1. — Schematic drawing showing the organization of the VA RNA genes on the adenovirus chromosome. (A) A simplified transcription map of the Ad5 genome. Arrows denotes the position of viral early (open) and late (thin) transcription units. (B) Expansion of the genome position encoding the VA RNA genes. (C) Nucleotide sequence at the promoter site of VA RNAI showing the position of the start site for VA RNAI(G) (bold arrow) and VA RNAI(A) (thin arrow). The sequence of the 5′-end of the major VA RNAI(G) start is indicated in bold letters. The nucleotides deleted in viruses lacking VA RNAI(A) expression are indicated by a delta sign (Δ).
