Mouse

"In this case we're using a mouse retrovirus to deliver the missing gene to your cells."

- Dr. Carson Beckett

A mouse (plural mice) is a small mammal belonging to the order of rodents. The best known mouse species is the common house mouse. It is also a popular pet. Mice are common experimental animals in biology and psychology primarily because they are mammals, and also because they share a high degree of homology with humans. The Atlantis expedition brought several mice with them on the initial expedition, some of which were used by Dr. Carson Beckett to create a delivery method for the ATA gene. Mice were later used to test the repairs done to the Wraith beaming device that contained the body of Lieutenant Laura Cadman, the mice did not survive the process.
