Salt Lake City, UT – Humans and mice have many genes in common. To inform our understanding of how these genes work, scientists in Mario Capecchi's laboratory at the University of Utah use genetic techniques to modify DNA in living mice. The mice are maintained in a building on the campus known as the Mouse House. In the fourth segment in our series on Mario Capecchi's groundbreaking work in genetics, Sheri Quinn takes us inside the facility where the mice are made.
