Molecular genetics

Genetic mutations can change how proteins and cells function. This infographic outlines how proteins are made from genes and explains certain types of genetic mutations that are found in cancer.

CRISPR. Starting with its definition, we explain how this technology harnesses an ancient bacteria-based defense system — and how it will impact the world around us today
