Question

Who showed rna as genetic material in plant viruses?

Answer 1

The discovery of the genetic functions of RNA in a plant virus (Tobacco mosaic virus, TMV) is commonly attributed to the American plant virologist Heinz Fraenkel-Conrat, and to the Germans Alfred Gierer and Gerhard Schramm, who came to the same conclusion independently in 1956. In reality, the first understandings dated back to about 1940, when several scientists discovered that TMV infectivity was closely related to the presence of undamaged RNA in the virus particles.

Answer 2

Answer:

The demonstration that DNA is the genetic material of a particular type of virus was provided by the elegant
