The type of five-carbon sugar that is present would best direct an investigation on whether the "informational polymer" is DNA or RNA.

DNA and RNA are two different types of nucleic acids, which are composed of different building blocks.

In RNA, Thymine nucleotide bases are replaced by Uracil bases (both are pyrimidine nucleotides).

In DNA, the sugar is a deoxyribose pentose, whereas in RNA the pentose sugar is called ribose.
