models

Organisms that scientists use to reproduce features of a disease of interest in an organism and then study it. For example, inserting the gene for HD into a mouse means that it will produce the altered HD protein in the brain. This creates an HD mouse model. The consistent use of these models allows researchers to test ideas about biology in a reproducible way, without the expense and ethical problems of performing these tests in humans.
