Genes are sequences of DNA that, for the most part, code for proteins. The flow of genetic information from DNA to RNA to protein has been referred to as the central dogma of molecular biology.
Mutations in genes can affect the resulting proteins and some mutations cause disease. To treat genetic diseases, scientists and doctors can intervene at different steps in the central dogma.
Scroll down to explore the steps in the central dogma pathway in a human cell. Click on the plus signs to explore a genetic medicine strategy that is being used to intervene at a particular step and a disease that could be treated using that strategy.
