WebOperons can be defined as multiple genes that are transcribed together, so yes in the absence of splicing there is a single mRNA produced. There are sequences between the genes in a prokaryotic operon called "ribosome binding sites" (RBSs) that recruit ribosomes to start translation of each gene separately.

WebJul 7, 2024 · The lac operon exhibits both systems. It is a negative control system because expression is typically blocked by an active repressor (the lac repressor) that turns off transcription. The lac repressor binds to the operator region and negatively controls (prevents) transcription. What increases gene expression?
