Understand that the question is asking for the full form of the abbreviation 'DNA'.
Recall that DNA is a molecule that carries genetic information in living organisms.
Break down the abbreviation: 'D' stands for 'Deoxy', 'N' stands for 'Ribo' or 'Ribonucleic', and 'A' stands for 'Acid'.
Combine these parts to form the full name: 'Deoxyribonucleic acid'.
Verify that this matches the known scientific term for DNA, which is the molecule responsible for storing genetic instructions.
