Q: Which region of dna consists of one or more genes that encode the proteins needed for a specific function?


Read this paragraph and choose the correct option from the provided answers:

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.

 Choices:

- mRNA

- chromosome

- antigen

- operon


A:
operon
