Detailed explanation-1: -8) Scientists implant a gene into a species of tomato plant that makes them ripen faster and stay firm as they are transported to stores. What is the benefit of this technology? Increased toxins in the food. Increase shelf life and availablity.

Detailed explanation-2: -A chemically synthesised cecropin B gene, usually found in the giant silk moth (Hyalophora cecropia), has been introduced into tomato plants and in vivo studies show significant resistance to bacterial wilt and bacterial spot.

Detailed explanation-3: -Genetic engineering allows scientists to move desired genes from one plant or animal into another. Genes can also be moved from an animal to a plant or vice versa. Another name for this is genetically modified organisms, or GMOs.

Detailed explanation-4: -… Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism.

Detailed explanation-5: -Polygalacturonase is responsible for the degradation of pectin, present in the cell wall of the fruit. As a result, it softens and makes the fruit susceptible to fungal infections. But, due to genetic engineering, the genetically modified Flavr Savr tomato has an extended shelf life with a reduced ripening rate.
