1.   We account for this by saying that their genes cause them to have such beliefs.

2.   We must in consistency admit that our genes cause us to have our beliefs, too.

3.   An epilepsy-associated gene was discovered last year in Finland, but the gene causes general nerve degeneration.

4.   And the gene is causing cell death in a number of tumors.

5.   And, as with any genetically engineered crop, the squash posed the risk that its new genes might cause it to spread and become difficult to control.

6.   Before genetic drugs can be developed to attack a specific disease, researchers must understand exactly how that gene causes the disease in the first place.

7.   But if doctors know exactly which gene is causing the cancer, then they can go after only cells in which those genes are active.

8.   But in times of plenty, those genes cause chaos.

9.   Gordon cautioned, however, that the studies do not prove that the mutated gene caused diabetes to occur earlier in adults who would have ordinarily gotten it.

10.   If each condition were caused by a single gene, then surely that gene could somehow be removed or switched off, curing the illness.
