Genetic engineering is raising
public concern. |
Genetic engineering is a form of biotechnology. It
focuses on the manipulation of the DNA or genetic material inside the cells of living
organisms. Genetic engineering blocks, adds, or even scrambles DNA to
add or block traits of the organism.
It is a modern and broad term describing processes such as plant fermentation
and hybridization or cross-breeding.
The best way to explain genetic engineering is to give examples of foods that
have been genetically engineered:
- Corn and soybeans engineered to contain altered levels of nutrients.
- Corn, soybeans, tomato, and canola plants that withstand herbicide application.
- Corn, tomatoes, and potatoes that have their own "built-in"
pesticides.
- Corn, tomatoes, potatoes, soybeans, grapes, cantaloupe, canola and other plants
that have been manipulated to resist plant viruses.
- Tomatoes, peas, peppers, and fruits engineered to improve processing and extend
shelf life.
- Various enzymes (proteins that speed up biological processes) used to make wine,
fruit juice, sugar, beer, and oil.
- Genetically engineered rennet for making cheese. Rennin is a coagulating
enzyme obtained from a young animal's stomach--usually a young calf. It is used to curdle
milk in foods such as cheese.
Do we know if our foods
have been genetically engineered?No.
Although most people feel they have a right to know if the foods they are
eating and feeding their families are genetically engineered, that right is not being
protected by the United States. Other countries are protecting their citizens.
