 Watch these 2 animations and try to explain what is going on.  Animation 1 Animation 1  Animation 2 Animation 2

 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 

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

 Code that matches codons in mRNA to amino acids on tRNAs
