Learning Goals Students will understand that translation of mRNA to protein is preformed by the ribosome Students will be able to name and explain the major cellular components required for protein synthesis Students will know what codons and anti-codons are, and why stop codons work to terminate translation. Students will understand that the functional structures of the ribosome are made of RNA Students will know the basic differences in mRNA required for translation in bacteria, archaea, and eukarya.
