Escherichia coli Tobacco Mosaic Virus Both of the above None of the above |
Tobacco Mosaic Virus |
The correct answer is option (2) -Tobacco Mosaic Virus In the case of Escherichia coli (E. coli), DNA is the genetic material. E. coli is a bacterium, and like most bacteria, it contains DNA as its genetic material. On the other hand, Tobacco Mosaic Virus (TMV) is an example of an organism in which RNA acts as the genetic material. TMV is a plant virus, and its genetic material is composed of RNA. TMV was one of the first viruses to be discovered, and its RNA genome plays a central role in the virus's ability to replicate and infect host cells. So, the correct answer is: Tobacco Mosaic Virus.
