41.   These genes make proteins that directly inhibit growth of the cell.

42.   They are used with a scanner to determine which genes make a specific protein or other building block of the human body.

43.   While the genes makes many paths possible, the brain is constructed from activity.

44.   Although genes clearly make people vulnerable to the disorder, none has been firmly identified yet.

45.   Another issue is whether the gene makes women more sensitive to the other effects of estrogen, Herrington said.

46.   Certain genes make some families vulnerable.

47.   In sickle cell disease, the gene makes an abnormal hemoglobin that is sticky and stiff.

48.   Now scientists need to understand how genes make proteins and what interactions among thousands of proteins trigger chemical reactions inside cells, he said.

49.   The gene made the rats pump out high quantities of a protein that promotes liver regeneration while reducing cell death.

50.   The genes apparently made muscle cells produce proteins that normally appear on or within the virus.
