Question

Assertion; Genetically modified tomato Flavr savr has increased shelf life and better nutrient quality.
Reason; This is achieved by reducing the degrading enzymes responsible for spoilage of food and refrigeration.
(a) Both assertion and reason are true and Reason is the correct explanation of the assertion.
(b) Both assertion and reason are true but Reason is not the correct explanation of the assertion.
(c) Assertion is a true statement but Reason is false.
(d) Both assertion and reason are false statements.

Answer 1

Hint: This transgenic tomato was not ready to produce polygalacturonase(PG), which is an enzyme involved in fruit softening, thanks to a deactivated gene. It is normally picked before ripening when they are still green and ripened artificially by ethylene treatment.

Complete answer:
Flavr Savr is a genetically modified tomato. It was the first genetically engineered food to get a license to be grown genetically for human consumption. An antisense gene was introduced in the Flavr Savr tomato to make it more impervious to decaying as it meddles with the creation of the enzyme polygalacturonase. This enzyme ordinarily corrupts pectin in the cell wall and results in the conditioning of organic products which makes them more helpless to being harmed by parasitic diseases. In this way, Flavr Savr tomatoes have expanded shelf-life of usability.

Additional Information: The genetically modified tomato went to the U.S. market on May 21, 1994, referred to as the Flavr Savr. This transgenic tomato was not ready to produce polygalacturonase(PG), which is an enzyme involved in fruit softening, thanks to a deactivated gene. Tomatoes are normally picked before ripening once they are still green and ripened artificially by ethylene treatment. The Flavr Savr tomatoes, however, are left to ripen on the vine and still have an extended time period, which was thought to permit them to develop their full flavor.
So the correct answer is ‘Assertion is a true statement but Reason is false’.

Note: The Flavr Savr tomato was indistinguishable in almost every aspect of the normal tomato. There were only two ways in which two tomatoes were different. The first difference was that the fruit cell membrane pectin degraded more slowly within the genetically modified tomato(this being the point of creating the new tomato). The second difference was that within the new tomato, the ingredient had a better viscosity. The only difference between the two tomatoes supposedly did not increase any risk, it just changed the taste.
