In some areas of the world, vitamin A deficiencies lead to a high number of deaths every year. To combat this problem, scientists created golden rice. In contrast to white rice, golden rice is created by adding two new beta-carotene genes, one from daffodil and one from a soil bacterium. The result is a rice that contains high levels of vitamin A. In order to create golden rice, which of the following processes is not employed? Polymerase chain reaction Splicing Gel electrophoresis Gene therapy

Golden Rice is a genetically modified organism (GMO). Which of the following steps was not involved in the development of this GMO? Targeted knockout of wild-type genes in the genetically modified rice strain. Inheritance of the integrated transgenes from one generation to the next. Identification and cloning of genes encoding enzymes that synthesize beta-carotene. Placing transgenes under the control of a promoter that drives transcription within the starchy endosperm of the rice grain. Integration of cloned transgenes into the rice genome.
