Faster, Cheaper Mutant Mice (IMAGE) University of Utah Health Caption A new, fast and inexpensive way to mutate genes and large, non-gene pieces of DNA has been developed by University of Utah geneticists. They tested the method by mutating a gene involved in bone formation, resulting in short, malformed tail and limbs in the mutant mouse on the left, compared with the skeleton of a normal mouse on the right. The new method promises to speed efforts to learn more about how non-gene portions of DNA control genes to cause human defects and diseases.
