Nucleotides may either be single-stranded or double-stranded. And depending on their sugar component, could either be DNA or RNA. DNA contains deoxyribose while RNA contains ribose. Aside from this, DNA uses the bases adenine (A), guanine (G), cytosine (C), and thymine (T). RNA on the other hand, has U instead of T.
Deduce whether each of the nucleic acid molecules in the table below is DNA or RNA, and single-stranded or double-stranded. Explain your reasoning.
