Concept 4: Basic Structure of a Protein-Coding Gene

A protein-coding gene consists of a promoter followed by the coding sequence for the protein and then a terminator.

The promoter is a base-pair sequence that specifies where transcription begins.

The coding sequence is a base-pair sequence that includes coding information for the polypeptide chain specified by the gene.

The terminator is a sequence that specifies the end of the mRNA transcript.
