Simplified representation of the negative-sense RNA genome of respiratory syncytial virus (RSV) and the encoded proteins.
The genome is shown 3′ with the leader extragenic region (ler) and with the 5′ trailer extragenic region (ter). The viral genes are depicted by the divided bars. Each viral gene transcribes a single messenger RNA (mRNA) encoding a single protein, with the exception of M2 mRNA, which transcribes two proteins, M2-1 and M2-2.
