How is genetic engineering done

And then taking what you have engineered and propagating that in any number of different organisms that range from bacterial cells to yeast cells, to plants and animals. So while there isn't a precise definition of genetic engineering, I think it more defines an entire field of recombinant DNA technology, genomics, and genetics in the s.

David M. Bodine, Ph. The seeds produced by these plants will inherit the new DNA. The characteristics of all living organisms are determined by their genetic makeup and its interaction with the environment.

The genetic makeup of an organism is its genome, which in all plants and animals is made of DNA. The genome contains genes, regions of DNA that usually carry the instructions for making proteins. It is these proteins that give the plant its characteristics. For example, the colour of flowers is determined by genes that carry the instructions for making proteins involved in producing the pigments that colour petals. This could include changing the way the plant grows, or making it resistant to a particular disease.

One of the methods used to transfer DNA is to coat the surface of small metal particles with the relevant DNA fragment, and bombard the particles into the plant cells. Another method is to use a bacterium or virus. There are many viruses and bacteria that transfer their DNA into a host cell as a normal part of their life cycle.

There are no reports of illness, injury, or environmental harm due to GE foods. Genetically engineered foods are just as safe as conventional foods. The US Department of Agriculture has recently started requiring food manufacturers to disclose information about bioengineered foods and their ingredients.
