B3b: Proteins and Mutations

The genetic material in the form of DNA codes for the production of proteins. This item looks at the structure and functions of proteins in living organisms, including the role of enzymes. It also introduces mutations and how they can alter the proteins that a cell produces. The study of enzyme action provides the opportunity to gain the skills of working accurately and safely, individually and with others, to collect first-hand data and to test a scientific explanation using scientific theories, models and ideas.
