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. Using recombinant technology, golden rice is created by added 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? * O Polymerase chain reaction O Splicing O Gel electrophoresis O Gene therapy

Genetic analysis

Genetic analysis refers to the process of studying and analyzing changes in chromosomes or genes using different methods in scientific fields such as genetics and molecular biology. It involves the localization and identification of genes and the detection of inherited or genetic disorders caused by mutations or other abnormal variations in our genome.
