Which region of dna consists of one or more genes that encode the proteins needed for a specific function?
antigen
mRNA
chromosome
operon
Regulation of transcription in prokaryotes typically involves operons. An operon is a region of DNA that consists of one or more genes that encode the proteins needed for a specific function. The operon also includes a promoter and an operator. The operator is a region of the operon where regulatory proteins bind. It is located near the promoter and helps regulate transcription of the operon genes.
