Proteins are large molecules that are responsible for many activities in our cells, tissues, organs, and bodies and they also play a central role in the structure and function of cells. Proteins are composed of 20 types of smaller molecules known as amino acids, which are ordered in a long chain known as the protein amino acid sequence. Each protein has its own sequence that determines its structure and its function. You will build a model that predicts what a protein does based on its amino acid sequence. These predictions will help researchers understand how proteins function, and could lead to the development of new medical treatments and therapies.
