A gene in lac operon

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.
