Key Terms
- Enzyme A class of proteins serving as catalysts, chemical agents that change the rate of a reaction without being consumed by the reaction.
- Gene A unit of heredity composed of DNA.
- Genetically Modified Organisms Organisms whose genomes incorporate and express genes from another species.
- Genetics The branch of biology concerned with the study of heredity and variation.
- Organism An individual living thing, such as a bacterium, fungus, protist, plant or animal.
- Species A particular kind of organism; members possess similar anatomical characteristics and have the ability to interbreed.
- Vector In recombinant DNA, a small, self-replicating DNA molecule, or a portion thereof, into which a DNA segment can be spliced and introduced into a cell; generally a plasmid or a virus.
Genetic Modification
How are organisms genetically modified?
Genetic engineering is the modification of an organism's phenotype by manipulating its genetic material. Some genetic engineering uses the principle of recombination.
Genetically Modified Foods
Genetic engineering offers a time-saving method for producing larger, higher-quality crops with less effort and expense. Yet such benefits must be balanced against the risks of changing the genetic makeup of organisms.
Food - genetically modified (GM)
Some foods include ingredients (for example, soy beans) that have been genetically modified (GM), or are made using ingredients derived from GM organisms (for example, GM yeast). GM ingredients come from organisms that have had their genetic material altered using non-traditional breeding methods known as gene technology.
How can you tell if they are real or modified?The article discusses the use of genetically modified organisms (GMOs) in food as of August 2014. Topics include legislation passed in Vermont requiring the labelling of GMO foods, a survey from Rutgers University showing that three out of four Americans support the labelling of GMO foods, the health risks associated with the consumption of GMO foods, and a study from researchers at Washington State University on the effect of GMOs on the environment.

In the past, cloning was a figment of science fiction. However, ever since Dolly, the cloned sheep, was introduced in 1998, it has become an astonishing reality. Scientists around the world are facing the frontier of human cloning. Should the line be drawn here? What about using genetic engineering to "program" one's own unborn child?
