A viral DNA is analyzed and found to have the following base composition, in mole percent: A= 32, G = 16, T = 40, C = 12. What can you immediately conclude about this DNA?

A should be matched with T, and G with C. Other possible pairing are GT and AC, but these are mismatches, are errors. I would conclude the DNA is unstable.
It's not necessarily unstable, it might just be a single strand of DNA.
