English: Gene expression involves the transcription of mRNA from DNA and then its translation at the ribosome. Unlike eukaryotes, prokaryotes don’t have a nucleus, which allows the ribosome to connect to one end of the mRNA while the other continues transcription. Key: 1 - RNA polymerase, 2 - Cytoplasm, 3 - Cell Membrane, 4 - DNA, 5 - Ribosome, 6 - Amino acid, 7 - Polypeptide chain, 8 - mRNA
