Explanation:
Detailed explanation-1: -Gene therapy is a technique that modifies a person’s genes to treat or cure disease. Gene therapies can work by several mechanisms: Replacing a disease-causing gene with a healthy copy of the gene.
Detailed explanation-2: -The three important techniques of biotechnology are: (1) Recombinant DNA Technology (Genetic Engineering) (2) Plant Tissue Culture and (3) Transgenic (Genetically Modified Organisms).
Detailed explanation-3: -One way that genetic engineering is already being used to treat disease in humans. Scientist inject a corrected gene into a person suffering from a disease. If the gene is taken up by the diseased body cell, the proper protein can be produced, reversing the disease.
