Question Answer
+RNAGenome: mRNA -- Encode: RNA-dep-RNA-Poly -- Mechanism: immediate translation of RdRp (replicate genome)
-RNAGenome: template for mRNA -- Encode & Carry RdRp -- Mechanism: RdRp makes +RNA, then replicates -RNA genome
retroviruses Type: +RNA lysogenic-- Genome: mRNA -- Encode reverse transcriptase (RNA --> dsDNA)
dsRNAGenome: dsRNA -- Encode RdRp only (already have mRNA to be translated)
Lytic vs productiveLytic- lysis of cell; Productive- buds out of cell (animal virus only)
Lysogenic Integrates as provirus and excised out for lytic or productive cycle
Prionsmisfolded verison of proteins
Viroidsnaked circular, ssRNA molecules = siRNAs to interfere with gene expression
