Benefits and negative consequences of developing genetically modified children:

By eliminating “bad” genes from sperm and egg cells—called the “germline”—the genetic modification tools have the potential to permanently wipe out diseases from these modified babies, caused by single mutations in genes, such as cystic fibrosis, Huntington’s disease.

On the other hand, there is huge uncertainty about what could go wrong if seemingly troubling genes are eliminated. There are also associated unknown social consequences as well as safety issues in genetically modifying the babies. For example: Consider sickle-cell anemia, an occasionally fatal genetic disorder. Its genes, though clearly harmful, have persisted and spread because, while having two copies of the sickle-cell gene causes anemia, having just one copy happens to provide protection against malaria, one of the most deadly diseases in human history. Had we not known about their benefits, eliminating sickle-cell genes would have proved to be a bad idea.

GMO labeling A genetically modified food is a food product developed from a different genetically modified organism (GMO) such as a crop plant, animal or microorganisms. The general principle of producing a GMO is to add novel genetic material into an organism's genome resulting in both new and useful traits. Some governments (like the entire EU, China and Japan) have emphasized risks over benefits from GM foods and require mandatory labeling and traceability, while others, such as the U.S., have...

genetically modified foods or GMOs raise concerns about long term health and environmental consequences.

Are they a necessary part of our food supply?

Genetically modified organisms are not new. According to the USDA, in 2009, 93 percent of soy, 93 percent of cotton and 86 perfect of corn grown in the United States was GMO. However, in 2010, life on earth as we currently understand it, changed. By inserting computer-designed genetic material into a bacterial cell, scientist created an entirely new strain of bacteria, a new life form, the world's first synthetic cell. In annoucing his creation, scientist Craig Venter called if the...

Scientists genetically modified a specific subspecies of fruit flies to ensure there are no mutations when DNA replicates. The scientists state this modification will wipe out any genetic variation in these particular modified flies.

In an experiment, E.coli cells have been genetically modified through site directed mutagenesis. This is a process through which specific locations in an organism’s genome can be altered in order to study the function of such locations, or proteins coded for by genes found in a location. There are many techniques available for site directed mutagenesis. (You have access to PCR ingredients, any primer you wish, laboratory equipment, Lambda phage, and the ability to alter Lambda genome, a commercially available...
