Coding region

The coding region of a gene is the portion of DNA or RNA that is transcribed into another RNA, such as a messenger RNA or a non-coding RNA (for instance a transfert RNA or a ribosomal RNA). A transcript can then be translated into proteins. This does not include gene regions such as a recognition site, initiator sequence, or termination sequence, only the region that will directly code for amino acid linkage. It is abbreviated as coding sequence 'CDS' in GenBank entries
