    turned___on __ a gene

    83 In one study, researchers took two genetically identical groups of female laboratory mice and randomly ______ them ___ receive two different kinds of food while pregnant. One group received a food rich in substances that _turned___on __ a gene that causes weight gain. The other group received a food rich in nutritional supplements (folic acid and vitamin B12) that protect against such weight gain. Results showed that the offspring of the pregnant mice that received the food that turned on the weight gain gene became fat. The food of the mother while pregnant, not the food of the animal after birth, ___ __ obesity. Equally noteworthy: The foods of pregnant mice that ___ rich in vitamin B12 and folic acid protect against obesity in offspring.

    Does "turn on" mean "to activate or stimulate"?
