Generalization of Viral Nucleic Acids

	Generalization of Viral Nucleic Acids -SINGLE-STRANDED DNA (ssDNA) Parvoviruses Adeno associated satellite viruses two kinds of virus particles, one containing plus and the other minus strands. All other Parvoviruses contain ssDNA of one polarity only. Phages φXI74, S13, M12, M13, f1, fd-circular ssDNA. DOUBLE-STRANDED DNA (dsDNA)
ANIMAL VIRUSES Papovavirus - closed, circular dsDNA. Adenovirus - linear dsDNA. Herpesvirus - linear dsDNA. Poxvirus - dsDNA. PLANT VIRUSES Cauliflower Mosaic Virus
PHAGES Phage Tl - linear dsDNA. Phages T2, T4, T6 - linear, terminally redundant, circularly' permuted dsDNA. Phages T3, T7 - linear dsDNA. Phage TS - linear dsDNA, one strand segmented. Phage lambda ( A ) - linear dsDNA, with cohesive ends. Phage PM2 - circular dsDNA.
SINGLE-STRANDED RNA (ssRNA) ANIMAL VIRUSES Picornavirus - infectious (+) ssRNA. Togavirus - infectious (+) ssRNA. Paramyxovirus - Noninfectious (-) ssRNA. Orthomyxovirus - Noninfectious (-), segmented ssRNA. Rhabdovirus - Noninfectious (-), ssRNA.
	PLANT VIRUSES TMV, TYMV, Brome mosaic virus - ssRNA PHAGES MS2, f2, fr, Q β-linear ssRNA DOUBLE-STRANDED RNA (dsRNA) ANIMAL VIRUSES Reovirus - 10 or more segments of dsRNA. Cytoplasmic polyhedrosis virus of insects - 10 segments. Blue tongue virus - 10 segments of dsRNA Retroviruses - complex of 2 segments plus 7S - and 4S host cell DNA

PLANT VIRUSES
Wound tumour virus - dsRNA.
Rice dwarf virus - dsRNA
PHAGE φ 6 - 3 linear segments of dsRNA.
