Which genes contain the information to make a protein?

• A. Structural genes
• B. Regulatory genes
• C. ABO blood type system
• D. Ancient DNA

Answer: (A)

Proteins are made when a gene’s sequence is transcribed into RNA and then translated into a polypeptide. The genes whose main role is to provide the blueprint for building these proteins are structural genes. They carry the information that directly codes for protein products that form the cell’s structure and perform many functions. Regulatory genes do code for products that control when and where other genes are turned on or off, often producing regulatory proteins, but their primary job isn’t to write the amino acid sequence of structural proteins themselves. The ABO blood type system describes a set of alleles related to antigens, not a single gene product itself, and ancient DNA refers to material rather than a specific gene’s product.
