This can provide information about the function of the altered gene, and often about the process under study.

Ultimately our own altered genes are doing the damage; they become the oncogenes.

Scientists then insert cells with the altered gene into a second embryo at a very early stage of development.

Tests have been developed that can detect altered genes.

After he fell sick, doctors failed to cure him due to his altered genes.

When subjected to enough damage at one time, the altered gene can cause the death of the cells.

Some altered genes related to breast cancer are more common in certain ethnic groups.

Often the goal is to create an animal that has the altered gene.

They can't get altered genes into cells without infecting them with a virus, and a lot of times that's a really bad idea.

The new study raises the possibility that the responders may be patients with the altered genes.
