They are isolating collections of mouse genes that cause those behaviors.

It is important because studies of mouse genes give leads about human genetics.

The company plans to identify all the mouse genes for comparison with human genes.

Researchers have recently learned how to target a mouse gene of choice and remove it from the embryo.

The one mouse gene I've cloned provides a concrete example of the challenges.

Ifi202 is a mouse gene (encodes for the p202 protein).

Researchers now believe that 10 to 20 percent of mouse genes are imprinted.

The structure of the mouse gene was already known.

Indeed, the human version of the mouse gene is also known to be imprinted by the father.

So far about 20 imprinted mouse genes have been detected.
