What are genes made up of?

• A. Large, complex molecules called DNA.
• B. Simple sugars and minerals.
• C. Proteins only.
• D. Lipids and fats.

Answer: (A)

Genes are made up of large, complex molecules called DNA. DNA, or deoxyribonucleic acid, is a long polymer built from nucleotides, and the specific sequence of these nucleotides stores the instructions for making and regulating organisms. A gene is a particular segment of DNA that carries those instructions. The other options miss the mark because simple sugars and minerals aren’t genetic material and have other roles in the cell; proteins are produced based on the information in DNA, not the material that genes themselves are made of; and lipids and fats are different types of molecules used for membranes and energy storage, not genetic material.
