Terminator (genetics)

In genetics, a terminator, or transcription terminator is a section of genetic sequence that marks the end of a gene or operon on the DNA for transcription.

Terminator sequences are distinct from termination codons that occur in the mRNA and are the stopping signal for translation, which may also be called nonsense codons.

A transcription terminator must also be distinguished from dye terminator sequencing , which is a method of sequencing DNA.
