1.   But the region was large, and pinpointing the gene would be arduous.

2.   It would be a basic scientist, for example, who would pinpoint the gene that causes a specific mutation in yeast.

3.   Kelly plays Dr. Jeannie Ferrami, an inquisitive biologist at a prestigious university who is trying pinpoint the gene that leads to aggressive behaviour.

4.   Researchers say they have pinpointed a gene that appears to have a major effect on obesity in both Mexican Americans and African Americans by regulating the hormone leptin.

5.   The goal is to pinpoint the genes that govern how an embryo develops into a fetus and perhaps how to prevent or treat birth defects.

6.   With only a single family to work with, and thus fewer genetic differences to go on, pinpointing the gene took six years.

7.   An international research group says it has pinpointed a gene that could be involved in a significant number of cases of adult-onset diabetes.

8.   Scientists say they have pinpointed genes that cause a serious intestinal disorder, marking the first time that the multiple genetic causes of a disease have been identified.
