Final answer:
ATP and DNA molecules share common structural characteristics such as sugar, phosphate groups, and nitrogenous bases.
Step-by-step explanation:
The common structural characteristics of ATP (adenosine triphosphate) and DNA (deoxyribonucleic acid) molecules are:
- Sugar: Both molecules contain a sugar component. ATP contains a five-carbon sugar called ribose, while DNA contains a five-carbon sugar called deoxyribose.
- Phosphate groups: Both molecules contain phosphate groups. ATP has three phosphate groups, while DNA has one phosphate group in each nucleotide.
- Nitrogenous base: Both molecules contain a nitrogenous base. ATP has adenine as its nitrogenous base, while DNA has adenine, cytosine, guanine, and thymine as its nitrogenous bases.
