An operon fusion has a transcriptional signal from one gene fused with the translational start and coding sequence from another.

Question

Quizplus · Accepted Answer

An operon fusion occurs when the regulatory sequence of one gene is fused to the coding sequence of another gene, resulting in a single transcriptional unit that is controlled by the regulatory sequence of the first gene. This allows the expression of the second gene to be controlled by the same environmental signals that regulate the first gene.
