The sample that is being discussed in the problem can be either DNA or RNA.

DNA and RNA are both very important molecules. Both of these hold immense value in biology since they store all the vital information required for living. The basic structures of the two are quite similar; the only difference is that DNA is double-stranded while RNA has a single strand.

DNA and RNA molecules both contain a five-carbon sugar (ribose), a phosphate group, and a nitrogenous base. Except for cytosine, guanine, and adenine, the fourth part is the phosphate group that exists in both. RNA has Uracil while DNA has Thymine.

Since it has not been mentioned here what the fourth part might be, the sample might be a DNA or an RNA molecule.
