    Golden rice is a transgenic crop of the future with high Vit. A content. Millions of people suffer from Vit. A deficiency which leads to vision impairment. Transgenic rice has been developed which is capable of synthesizing beta carotene, the precursor of Vitamin A. The transgenic rice variety is now being crossed with adapted varieties through field tests to make them grow in an year or two.

    Genetic engineering has been successfully used for producing transgenic mice. Many transgenic mice are designed to increase our understanding of how genes contribute to development of diseases. Transgenic mice are being developed for use in testing the safety of vaccine before they are used in human beings. For example transgenic mice are being used to test the safety of polio vaccine.
