Viral Replication Cycle
Both the (+) and the (–) strands of L-A are synthesized within viral particles. Mature particles containing L-A dsRNA synthesize (+) strands (transcription) by a conservative mechanism, and extrude the new strand from the particles. These (+) strands serve as mRNA, to make coat proteins, and as the species encapsidated by those proteins to make new nucleoprotein particles. Encapsidated (+) strands are converted to dsRNA form (replication). The absence of both 5′ cap and 3′ poly(A) on the viral mRNA is the basis of complex interactions of virus and host in translation.

Famous quotes containing the word cycle:
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
