Which of the following was not a technique researchers used to try to improve shelf life of tomatoes with genetic engineering?
A) Insertion of a second polygalactouronase gene
B) Using an antisense gene
C) Inhibition of the production of ethylene
D) Storage in a 40 degree Celcius compartment

Question

Quizplus · Accepted Answer

Techniques A, B, and C are genetic engineering methods aimed at improving the shelf life of tomatoes by altering their ripening process. Inserting a second polygalacturonase gene, using an antisense gene, and inhibiting the production of ethylene are all genetic modifications intended to slow down ripening. Technique D, storing tomatoes in a 40-degree Celsius compartment, is not a genetic engineering method but rather a physical method of storage, which does not involve altering the tomato's genetic makeup.
