Pros Cons With the discovery of DNA and unravelling the genetic code it contains, molecular biologists have finally come close to understanding what determines the form and function of organisms and can use this to design organisms at will.
These crops have more direct benefits to consumers.

GM crops are made through a process known as genetic engineering. Genes of commercial interest are transferred from one organism to another. Two primary methods currently exist for introducing transgenes into plant genomes.
The DNA to be introduced into the plant cells is coated onto tiny particles of gold or tungsten. These particles are then physically shot onto plant cells and incorporated into the genomic DNA of the recipient plant.
The second method uses a bacterium to introduce the gene s of interest into the plant DNA. While most of the debate over transgenic crops has taken place mainly in the developed nations in the North, the South stands to benefit from any technology that can increase food production, lower food prices, and improve food quality.
In countries where there is often not enough food to go around and where food prices directly affect the incomes of majority of the population, the potential benefits of GM crops cannot be ignored.
It is true that nutritionally enhanced foods may not be a necessity in developed countries but they could play a key role in helping to alleviate malnutrition in developing countries. Although the potential benefits of GM crops are large in developing countries, they would require some investments.
Most developing countries lack the scientific capacity to assess the biosafety of GM crops, the economic expertise to evaluate their worth, the regulatory capacity to implement guidelines for safe deployment, and the legal systems to enforce and punish transgressions in law.
Fortunately, several organizations are working to build local capacity to manage the acquisition, deployment, and monitoring of GM crops.
What are the potential risks of GM Crops? With every technology, there are potential risks. The potential risks of GM crops include: The danger of unintentionally introducing allergens and other antinutritional factors in foods The likelihood of transgenes escaping from cultivated crops into wild relatives The potential for pests to evolve resistance to the toxins produced by GM crops The risk of these toxins affecting nontarget organisms.
Where legislation and regulatory institutions are in place, there are elaborate steps to precisely avoid or mitigate these risks. It is the obligation of the technology innovators i. There are also those risks that are neither caused nor preventable by the technology itself.
An example of this type of risk is the further widening of the economic gap between developed countries technology users versus developing countries nonusers. These risks, however, can be managed by developing technologies tailor made for the needs of the poor and by instituting measures so that the poor will have access to the new technologies.
Conclusion Despite the current uncertainty over GM crops, one thing remains clear. This technology, with its potential to create economically important crop varieties, is simply too valuable to ignore.Before I go more in depth about the pros and cons of genetically modified crops, let me first give a definition of what genetically modified crops are.
Genetically modified crops (often abbreviated as GMOs) are simply crops, whose genetical material has been modified. GMO insulin is also known as synthetic insulin, or human insulin.
It is produced with genetically modified bacteria, instead of the traditional method that produces what is known as pork insulin.
In this method, sometimes called natural insulin, the pancreas of a cow or pig is used to produce insulin. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Examples of GM crops include corn varieties containing a gene for a bacterial pesticide that kills larval pests, and soybeans with an inserted gene that renders them resistant to weed-killers.
Since then, several transgenic crops have received FDA approvals, including “Canola” with modified oil composition, cotton and soybeans resistant to herbicides, etc. GM foods that are available in the market include potatoes, eggplants, strawberries, carrots, and many more are in pipeline.
The Advantages of Genetically Modified Foods: 1. Huge Amount of Nutritious Foods In the huge variety of genetically modified foods nowadays, the consumers will be able to find several examples if healthy foods that are full of several kinds of nutrients compared to the ordinary crops .
