WebThe first step in reading a gene is to transfer the information from DNA to messenger RNA (mRNA) using a protein called RNA polymerase (in humans, the polymerase that reads genes like lactase is RNA polymerase II). This process is called transcription. The mRNA then heads over to a protein making machine in the cell called a ribosome. WebOnce in the cytoplasm, the mRNA attaches to one or more ribosomes Step 4 in the flow of information within a eukaryotic cell from a gene to a polypeptide chain Translation; now protein synthesis can begin. tRNA brings the appropriate amino acids as specified by the mRNA's code to the ribosome, and a polypeptide chain is synthesized
