Free statement of participation on completion

In this free course we explore proteins and how they are the 'doers' of the cell. They are huge in number and variety and diverse in structure and function, serving both the structural building blocks and the functional machinery of the cell. Just about every process in every cell requires specific proteins. The basic principles of protein structure and function which are reviewed in this course are crucial to understanding how proteins perform their various roles.
