. In bacterial genes, as soon as any partial mRNA transcriptis produced by the RNA polymerase system, the ribosome assembles on it and starts translating. Draw a diagram of this process, identifying 5′ and 3′ ends of mRNA,the COOH and NH2 ends of the protein, the RNA polymerase, and at least one ribosome. Why couldn’t this system work in eukaryotes?
