Proteins are made of amino acids hooked end-to-end like beads on a necklace. To simulate. a protein, you will make a model of your protein using a long chenille stem (the fuzzy. covered wire) and colored beads.
Protein production starts in the cell's command center, the nucleus. Your genes, which are made of DNA, contain the instructions for making proteins in your body, although many other factorsâsuch as your diet, activity level, and environmentâalso can affect when and how your body will use these genes.
