You have isolated the genome from a novel virus and would like to determine its composition. You have three tu each containing one of these substances:
1) a protein that degrades dsDNA DNase, tube 1)
2) a protein that degrades ssRNA RNase, tube 2)
3) a protein that degrades other proteins protease, tube 3)
You add some of your novel genome to tubes 1, 2, and 3. The genome is not degraded in tube 1, 2, or 3. Based on your knowledge of genome types that have been found in viruses, what could the genome's composition be?
A) dsDNA that is resistant to DNase
B) dsRNA
C) ssDNA
D) It could be any of the above.

Since the genome was not degraded in any of the tubes, it suggests that it is not susceptible to DNase, RNase, or proteases. This means it could be any type of genome (dsDNA, dsRNA, ssDNA) that is resistant to these enzymes or not targeted by them.
