Genetically Modified Foods

So, I've been doing some research about the types of GM Foods and what scientists have done with them. Here are a few of them:

Wine - Yes, it is a GM Food because it is the process through the fermentation of grapes

The Marine Strawberry - A strawberry that can reproduce as many times as it wants. It is a strawberry cell infected with an antifreeze gene (from a type of North American flatfish) which integrates into the strawberry's DNA and the plants transgenesis takes place, which makes it reproduce and withstand extreme temperatures.

BT (bacillus thuringiensis) Corn - GE'd corn that is resistant to the western corn root (a pest that feeds of roots of corn plants). BT Corn produces the BT Toxin, naturally produced by a soil bacterium. When pests try to eat the corn, they die by consuming the toxin.

Golden Rice - First organism that was modified to provide more vitamin A for people with that vitamin defiencieny.

Flavr Savr Tomatoes - First GM crop that was introduced in 1994. A normal tomato is picked when it is still ripe and green, then treated with ethylene (natural ripening gas) that makes it turn red and appealing. Flavr Savr tomatoes contain a gene that slows over-ripening, so that tomatoes can ripen on the vine and have better flavour.
