Answer: The viral nucleic acid is most likely Deoxyribonucleic acid (DNA)
Explanation:
Unlike ribonucleic acid (RNA) where uracil can be found, thymine alongside adenine, cytosine and guanine are only found in DNA.
Thus, the presence of 10% thymine in the newly discovered virus makes its analyzed nucleic acid to be deoxyribonucleic acid (DNA)
