Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Tobacco Mosaic Virus (TMV) genes are
A
double stranded RNA
B
single stranded RNA
C
polyribouncleotides
D
proteinaceous
Explanation: 

Detailed explanation-1: -TMV is a positive-sense, single-stranded RNA virus that belongs to the genus Tobamovirus of the Virgaviridae family. TMV has a very wide host range and its primary host is Nicotiana tabacum.

Detailed explanation-2: -Tobacco mosaic virus (TMV) has single stranded RNA (ss RNA) as its genetic material.

Detailed explanation-3: -Tobacco mosaic virus (TMV) has a 6.3-kb positive-stranded RNA genome which encodes four proteins (reviewed in references 1, 2, and 6). The 126-and 183-kDa proteins have essential replication functions and are translated from the virus genomic RNA.

Detailed explanation-4: -The TMV (Tobacco Mosaic Virus) is a positive single-stranded RNA virus mostly infecting tobacco plants and members of the Solanaceae family.

Detailed explanation-5: -Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus that infects tobacco and other members of the family Solanaceae.
