Generated Narrative: CodeSystem gene-element-type

This case-sensitive code system http://hl7.org/fhir/gene-element-type defines the following codes:

Code	Display	Definition
promoter	Promoter	A DNA sequence that initiates and regulates transcription of a gene.
enhancer	Enhancer	A DNA sequence that increases the rate of transcription.
silencer	Silencer	A DNA sequence that reduces or prevents transcription.
terminator	Terminator	A DNA sequence that signals the end of transcription.
repressor	Repressor binding site	A DNA sequence to which a repressor protein binds to inhibit transcription.
coding-sequence	Coding sequence (CDS)	The portion of a gene that encodes a protein.
intron	Intron	A non-coding sequence within a gene that is spliced out during mRNA processing.
ribozyme	Ribozyme	A catalytic RNA element.
