Final answer:
DNA, NADH, and ATP are all involved in cellular energy processes and have specific functions. DNA carries genetic information, while NADH transfers electrons, and ATP is the primary energy currency of cells.
Step-by-step explanation:
DNA, NADH, and ATP have several commonalities. They all play essential roles in cellular energy processes. ATP (adenosine triphosphate) is the primary energy currency of cells, involved in storing and transferring energy. NADH (nicotinamide adenine dinucleotide) is responsible for transferring electrons during metabolic reactions, while DNA carries genetic information and is involved in protein synthesis
