Which statement is true about DNA’s content?

Which statement is true about DNA’s content?

• A. our protein sequences
• B. our RNA sequences
• C. our metabolic pathways
• D. our genetic code

Answer: (D)

DNA stores information in the form of its nucleotide sequence, which is the genetic code—the set of instructions that tells cells how to build proteins and functional RNA. This code maps codons (three-nucleotide units) to specific amino acids, guiding protein synthesis and regulation. So the true statement is that DNA’s content is our genetic code, the information that determines how organisms develop and function. Protein sequences are the products of that code, not the stored content themselves, and RNA sequences or metabolic pathways are outcomes of gene expression rather than direct DNA content.
