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.
Proteins are made inside cells. When a cell makes a protein it is called protein synthesis. The instructions for how to make a protein are held inside the DNA molecule. The two major stages in making a protein are called transcription and translation. The first step in making a protein is called transcription.
