Which process describes decoding genetic information into a protein?

• A. Gene expression
• B. Replication
• C. Transcription
• D. Mutation

Answer: (A)

Gene expression is how genetic information is decoded and used to make a functional product, usually a protein. It has two main stages: transcription, where DNA is copied into messenger RNA, and translation, where that RNA guides the assembly of amino acids into a protein. This makes gene expression the best fit for turning genetic information into a protein because it covers both the information transfer and the actual production of the protein. The other ideas describe different cellular processes: replication copies DNA for cell division; transcription alone yields RNA and doesn’t by itself produce a protein; mutation is a change in the DNA sequence.
