A structural gene is a gene that codes for a polypeptide
gene product. It can be divided into sections
involved in transcription (transcription
unit) and regulatory sequences. Regulatory
sequences are located both upstream (the 5!
direction) and downstream (the 3! direction) of
the gene. In addition, internal regulatory
sequences may occur in introns. Some regulatory
sequences are located far from the gene.
