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. WebThe lac operon is used for the transportation and metabolization of lactose. An operon is a clump of genes managed by a singular promoter. Promoters are a region of DNA where …
