WebEukaryotic mRNA that has been processed and transported to the cytoplasm (i.e., mature mRNA) can then be translated by the ribosome. Translation may occur at ribosomes free-floating in the cytoplasm, or directed to the endoplasmic reticulum by … WebThe ribosome moves down the mRNA by one codon, and all three tRNAs move down one position and the tRNA in the E site exits.Protein synthesis is catalyzed by RNA. The translation of each m RNA codon begins when an aminoacyl t RNA diffuses into the A site and stays if its anticodon matches a codon in the mRNA .
