My protein synthesis analogy is a softball team. My analogy is about the softball team playing defense (in the field) not offense (up to bat). The nucleus is the dugout because the coach is in it and the players exit and enter it. The DNA is the coach because he makes all the plays and decides the lineup, or everyone’s position in the field. The mRNA is the catcher, who receives the signal from the coach and sends it to the pitcher and the other fielders. The ribosome/rRNA is the pitcher because she carries out the play by throwing a pitch, which also binds all the players around her together. The tRNA is the shortstop, who sees the signal from the catcher and moves the other fielders/addresses the play. The amino acids are all the other fielders
