Open in App
Solution
The correct option is C Polygalactouranase
Flavr Savr is a genetically modified tomato. It was the first commercially grown genetically engineered food to be granted a license for human consumption. The Flavr Savr tomato was made more resistant to rotting by adding an antisense gene which interferes with the production of the enzyme polygalacturonase. This enzyme normally degrades pectin in the cell walls and results in the softening of fruit which makes them more susceptible to being damaged by fungal infections. Thus, Flavr Savr tomatoes have extended shelf-life. Therefore, the correct answer is option C.
