What is Genetic Engineering?
Genetic engineering is the process of modifying an organism’s DNA to introduce new, desirable traits. Many organisms, from bacteria to plants and animals, have been genetically modified for academic, medical, agricultural, and industrial purposes. While genetic engineering has definite benefits, ethical concerns surround modifying humans and our food supply.Scientists can Deliberately Modify an Organism’s GenomeGenetic engineering is possible because the genetic code—the way information is...
Transgenic Organisms
Transgenic organisms are genetically engineered to carry transgenes—genes from a different species—as part of their genome. The transgene may either be a different version of one of the organism’s genes or a gene that does not exist in their genome. Transgenes are usually generated by recombinant DNA and DNA cloning techniques. Transgenic bacteria, plants, and animals allow scientists to address biological queries and design practical solutions.Creating a Transgenic OrganismScientists begin the...
