PROTEIN SYNTHESIS (TRANSLATION) ANIMATIONS Watch these 2 animations and try to explain what is going on. Animation 1 Animation 2 STEPS OF PROTEIN SYNTHESIS HOW DOES MRNA TELL THE CELL WHAT TO DO? mRNA is a message that codes for a protein Proteins are made in the cytoplasm and then work to keep the cell alive Translation (protein synthesis): Process of making a protein Proteins are made up of amino acids (small building blocks) There are 20 different types of amino acids PROCESS OF TRANSLATION 1. mRNA moves out of nucleus and into cytoplasm 2. mRNA attaches to a ribosome 3. Transfer RNA (tRNA) decodes the mRNA and brings amino acids to build up the protein Anticodon (3 bases on tRNA): Matches up to codons on mRNA 4. Protein (chain of amino acids) detaches from ribosome and goes off to work in the cell GENETIC CODE Code that matches codons in mRNA to amino acids on tRNAs REVIEWING THE PROCESS Website PRACTICING THE PROCESS Site 1 Site 2 Site 3
