Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid.

If you have discovered a new virus and have isolated its nucleic acids What feature could you look for to determine if the nucleic acids of this virus are RNA or DNA?

One way to determine if the nucleic acids of the virus are RNA or DNA is to check for the presence of thymine in the nucleic acid sequence. Thymine is only found in DNA, so its presence would indicate that the virus has a DNA genome. Conversely, the presence of uracil instead of thymine would indicate an RNA genome.
