Genetically-modified tomatoes do not taste as good as regular tomatoes
|
|
|
Genetically-modified tomatoes are more expensive than regular tomatoes.

The DNA used to modify the tomatoes could change the DNA of the person eating the tomato.

|
|
None of the above

Detailed explanation-1: -DNA Plant Technology (DNAP), Agritope and Monsanto developed tomatoes that delayed ripening by preventing the production of ethylene, a hormone that triggers ripening of fruit.
Detailed explanation-2: -GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.
Detailed explanation-3: -What best describes a concern people have with eating genetically-modified tomatoes? The DNA used to modify the tomatoes could change the DNA of the person eating the tomato.
Detailed explanation-4: -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.
