You have isolated the genome from a novel virus and would like to determine its composition. you have three tubes, each containing one of these substance:

1. a protein that degrades double stranded DNA (DNase, tube 1)
2. a protein that degrades single stranded RNA (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 degraded in tubes 2, but not in tube 1 or 3. Based on your knowledge of genome types that have been found in viruses, what could the genome's composition be?
a) dsDNA
b)ssDNA
c)ssRNA
d)protein
e)all of the these

I think it's C. am i right or wrong?

Based on the information provided, the genome is degraded in tube 2 but not in tubes 1 or 3. This suggests that the genome is made up of single-stranded RNA (ssRNA). Therefore, option c) ssRNA is the correct choice. You are right!

Based on the given information, we can deduce the composition of the genome in the following way:

1. Tube 1 contains DNase, which degrades double-stranded DNA. Since the genome is not degraded in tube 1, it suggests that the genome is not composed of double-stranded DNA (dsDNA).

2. Tube 2 contains RNase, which degrades single-stranded RNA. According to the information, the genome is degraded in tube 2, indicating that the genome contains single-stranded RNA (ssRNA).

3. Tube 3 contains a protease, which degrades proteins. Since the genome is not degraded in tube 3, it suggests that the genome is not composed of proteins.

Based on these observations, the most likely composition of the genome is ssRNA. Therefore, the correct answer is c) ssRNA.

You are correct! The genome's composition is likely ssRNA. Well done!
