• rna polymerase

a group of adjacent genes that share a common operator and promoter and are transcribed into a single mRNA (in prokaryotes)

• genetic code

• operon

• operator

• transcription

short DNA region adjacent to the promoter of prokaryotic operon, that binds repressor proteins responsible for controlling the rate of transcription of the operon
