Summary

RNA Polymerase unwinds DNA and synthesizes a strand of mRNA. The mRNA leaves the nucleus and goes to a Ribosome. The Ribosome then brings tRNA molecules with amino acids to read the mRNA. The amino acids break off of the tRNA and make a chain of amino acids that fold upon its self and make a protein.
