Question

question 14 of 30 what is the function of nucleic acids in living organisms? a. to catalyze chemical reactions and transport molecules b. to store energy and provide structural support c. to provide energy and attack viruses and bacteria d. to store genetic information and synthesize proteins

Explanation:

• Option A: Catalyzing reactions and transporting molecules are functions of enzymes (proteins) and some other molecules, not nucleic acids.
• Option B: Storing energy (e.g., lipids, carbohydrates) and providing structural support (e.g., proteins, cellulose) are not functions of nucleic acids.
• Option C: Providing energy (e.g., glucose) and attacking pathogens (e.g., antibodies, immune cells) are not nucleic acid functions.
• Option D: Nucleic acids (DNA and RNA) store genetic information (DNA) and are involved in protein synthesis (RNA: mRNA, tRNA, rRNA play roles in transcription and translation).

Answer:

D. To store genetic information and synthesize proteins
