The prokaryotic gene and its ribonucleic acid (RNA) product are as follows:
The promoter is the region at which the RNA polymerase attaches itself and initiates transcription of the gene. The RNA polymerase starts transcribing the coding region and once it transcribes the complete gene, it would be cut off from the deoxyribonucleic acid (DNA) helix with or without the help of specific proteins.
