Question

All the structural genes of the operon are transcribed on a single long mRNA.

• A. True
• B. False

Answer 1

The correct option is A True

An operon is a set of genes that are transcribed under control of a single promoter. It results in one long mRNA that contains coding sequences for multiple genes. Upstream of the structural genes lies a promoter sequence which provides a site for RNA polymerase to bind and initiate transcription. Close to the promoter lies a section of DNA called an operator.

So, the correct option is 'True'.
