Respiratory syncytial virus RNA genome

Respiratory syncytial virus RNA genome is a nonsegmented, negative-sense single-stranded RNA approximately 15.2 kb in length, serving as the genetic blueprint for the virus[1][2]. It is encapsidated by nucleoprotein in a helical nucleocapsid, and acts as the template for viral RNA-dependent RNA polymerase-driven replication and transcription, which generates viral mRNAs and genomic copies critical for virus propagation. The genome is the foundation for all RSV gene expression and is actively targeted by antiviral drugs aiming to block its replication or transcription, such as nucleoside analogs and polymerase inhibitors[1][2]. This designation should be refined for structured databases; generally, drug development and mechanistic studies will specify direct protein targets (e.g., "Respiratory syncytial virus RNA-dependent RNA polymerase") or more detailed molecular features of the viral RNA. The viral RNA itself is an indirect target, as interventions usually block its synthesis or translation rather than the RNA alone[1][2][4].
