LIFE SCIENCE

Detailed explanation-1: -Modern genetic engineering is more precise than selective breeding in the sense that biologists can modify just a single gene. Also, genetic engineering can introduce a gene between two distantly-related species, such as inserting a bacterial gene into a plant (figure 14.3. c).

Detailed explanation-2: -Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world’s growing population.

Detailed explanation-3: -Which outcome is possible using genetic engineering, but not using selective breeding? A bacterium that produced human insulin. What is the term used to describe the complete genetic information of a cell or organism?
