Gene expression
ConceptCells use genetic information to produce functional RNA and, for many genes, proteins.
Explanation or usage
For protein-coding genes, transcription produces an RNA transcript from DNA information, and translation uses messenger RNA to assemble a polypeptide. Regulation at several stages can change how much product is made. Not every gene encodes a protein, and copying DNA for cell division is a different process.
Common misunderstandings
Transcription makes a protein directly.
Every gene encodes a protein.

Proposed Chapter 1 context: connect shared genetic information with different cellular functions. Retain the existing public definition and distinguish expression from DNA replication.
