What does DNA contain?

What does DNA contain?

• A. The energy storage for the cell
• B. The instructions for the production of proteins
• C. The instructions for lipid synthesis
• D. The components of the cell membrane

Answer: (B)

DNA stores genetic information that serves as the blueprint for making proteins. The genes pass their instructions to RNA, which is then used to assemble proteins on ribosomes. Proteins perform most cellular tasks—from catalyzing reactions to providing structure and signaling. Energy storage isn’t in DNA ( ATP is the energy currency ), and the components of the cell membrane are lipids and proteins rather than something DNA directly encodes. So the best description is that DNA contains the instructions for producing proteins.
