1.   A normal gene produces a normal protein, then something goes wrong and the body starts turning out prions.

2.   Finally you must get the gene to produce the protein it encodes at a biologically appropriate level.

3.   Homeobox genes produce mole- cules called transcription factors that turn other genes on and off.

4.   Homeobox genes produce molecules called transcription factors that turn other genes on and off.

5.   In the rare familial breast cancers, the gene produces a faulty form of the protein.

6.   Its scrambled genes produce three-foot crinkly white leaves with green blotches.

7.   One defective gene produces one abnormal protein that results in a disease.

8.   Or to find families who are disappointed with what the genes produce.

9.   Patients with cancer are supposed to be excluded from the therapy trials, because the genes used produce a protein that potentially could speed the growth of a tumor.
