This in turn serves as template for synthesis of a 45-nucleotide minus sense leader
RNA, and also for synthesis of full-length progeny genomes. Full-length genomes can either serve
as templates for secondary transcription, or can be assembled into infectious particles. Factors
determining the RdRP functions in transcription or replication modes are not fully understood but
the proportion of N protein and available RNP templates are thought to be critical for determining these functions. Following replication, further rounds of transcription (secondary transcription),translation and replication ensue.
