No ds replicative intermediate - breaks apart before completion of replication, so not degraded by host enzymes that destroy dsRNA. 1. Infecting RNA is polycistronic with 3 RBS - No regulatory proteins produced. Coat gene translation unveils replicase gene for translation. Replicase represses coat protein translation. Build up of coat protein represses further replicase translation.
Phage replicates as part of host genome.
Also binds to OL and PL to block other lytic gene expression 5. Also helps to switch from early to late gene expression. 6. cII required to begin synthesis of cI by binding PRE 7.
