Nobel Prize in Chemistry and HL Biochemistry

This years Nobel prize in chemistry has been awarded to three researchers, Frances Arnold, George Smith and Gregory Winter for their work on enzyme research. Their work uses a technique called ‘directed evolution’ to create new enzymes. It does also tie in nicely with some of the subject material covered in the HL biochemistry option. As I understand it, the work involves causing a gene (in a bacteria) to mutate randomly by using chemical mutagens or a technique called PCR. The ...
