Transcript of GMOs Food
What are genetically-modified foods?
The term GM foods or GMOs (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques.
These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content
What is the chemistry knowledge
relate to GMOs foods?
Genetically engineered plants are generated in a laboratory by altering their genetic makeup and are tested in the laboratory for desired qualities.
This is usually done by adding one or more genes to a plant's genome using genetic engineering techniques. Most genetically modified plants are generated by the biolistic method and chemistic method.
Why is the GMOs foods that important in daily life?
Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. GM foods promise to meet this need in a number of ways:
Drought tolerance/salinity tolerance
3. How do we use chemistry in everyday life?
-Creating plants better resistant to weeds, pest and other diseases.
-Bigger yields to create more efficient use of land, less uses of herbicides and other pesticides.
-Foods with better texture, flavor and nutritional value.
Foods with a longer shelf life for easier shipping.
GM foods can create an essential sustainable way to feed the world.
There are many viruses, fungi and bacteria that cause plant diseases. Plant biologists are working to create plants with genetically-engineered resistance to these diseases
Unexpected frost can destroy sensitive seedlings. An antifreeze gene from cold water fish has been introduced into plants such as tobacco and potato. With this antifreeze gene, these plants are able to tolerate cold temperatures that normally would kill unmodified seedlings
Drought tolerance/salinity tolerance
As the world population grows and more land is utilized for housing instead of food production, farmers will need to grow crops in locations previously unsuited for plant cultivation. Creating plants that can withstand long periods of drought or high salt content in soil and groundwater will help people to grow crops in formerly inhospitable places
Malnutrition is common in third world countries where impoverished peoples rely on a single crop such as rice for the main staple of their diet. However, rice does not contain adequate amounts of all necessary nutrients to prevent malnutrition. If rice could be genetically engineered to contain additional vitamins and minerals, nutrient deficiencies could be alleviated.
Medicines and vaccines often are costly to produce and sometimes require special storage conditions not readily available in third world countries. Researchers are working to develop edible vaccines in tomatoes and potatoes. These vaccines will be much easier to ship, store and administer than traditional injectable vaccines.
Background knowledge of Genetically Modified Organisms
A genetically modified organism (GMO) is a plant or animal that has been created using molecular biology techniques in order to enhance or choose a desired trait The most well known genetic engineering occurs on plants or crops where they add a gene in order to enhance the crops performance; for example: pesticide resistance or drought tolerance.
