What do genes code for?

• A. Proteins.
• B. Carbohydrates.
• C. Lipids.
• D. Ribonucleic acid (RNA) only.

Answer: (C)

Genes carry the instructions to build the cell’s functional products. Through transcription, a gene’s DNA sequence is copied into RNA, and then through translation that RNA is used to assemble a chain of amino acids into a protein. Proteins carry out most cellular roles—enzymes, structural components, receptors, and signaling molecules—so they are the primary products genes code for. There are exceptions: some genes produce RNA molecules that work directly (like rRNA, tRNA, and regulatory RNAs) and are not translated into proteins. Lipids and carbohydrates aren’t direct products coded by a gene; their synthesis depends on enzymes whose production is coded by genes. So, the core answer is that genes mainly code for proteins, with some genes coding for RNA instead.
