nucleic acid molecules in a eukaryotic cell

A biology student found two fragments of nucleic acid molecules in a eukaryotic cell; the fragments were labelled as “X” and “Y”. Upon further investigation, it was found that the chemical composition of fragment X was CGAATTGCCAATTGAGCT, and of fragment Y was UGGUUACCAGUAGCAA.1. Which one of the fragment do you believe is DNA and which one RNA, what is the difference(s) between the two fragments?2. Where would find fragment “X” in the eukaryotic cell, give two examples? 3. Where would find fragment “Y” in the eukaryotic cell, give two examples?4. What purpose do you think the cells use fragment X for ? 5. What purpose do you think the cells use fragment Y for?
