Gene Therapy: Introduction

Author(s): Timothy Davis

DNA makes up genes, which are blueprints for building proteins that keep the body running. In most cases, each individual inherits two copies of each gene from their parents. Hair color, height, and unique features are all controlled by these genes. However, genes are not always constructed appropriately. A mutation, or tiny change in them, might modify how proteins are expressed (made), affecting the body's capacity to operate effectively. This has the potential to change how a person breathes, walks, and even digests food. Genes can change as a result of hereditary mutations (changes passed down from one generation to the next), as they age, or as a result of chemical or radiation damage.
