Question

Tobacco mosaic virus has RNA rather than DNA as its genetic material. In a hypothetical situation where RNA from a tobacco mosaic virus is mixed with proteins from a related DNA virus, the result could be a hybrid virus:_________
A. Tobacco mosaic virus
B. The related DNA virus
C. A hybrid: tobacco mosaic virus RNA and protein from the DNA virus
D. A hybrid: tobacco mosaic virus protein and nucleic acid from the DNA virus
E. A virus with a double helix made up of one strand of DNA complementary to a strand of RNA surrounded by viral protein

Answer 1

Answer:

The correct answer is A. Tobacco mosaic virus

Explanation:

Virus can have DNA and RNA as its genetic material. Tobacco mosaic virus has RNA as its genetic material. Protein is not a genetic material because it is a product coded by genetic material.  

So a hybrid can be made only when the genetic material of two different organisms is mixed not two different biomolecules. Therefore when RNA from the tobacco mosaic virus is mixed with the protein from a DNA virus the result would be a tobacco mosaic virus only.
