Genetic engineering can have less impact on the expression of genomes or on protein and metabolite levels than conventional breeding or (non-directed) plant mutagenesis. [157] Toxicologists note that "conventional food is not risk-free; allergies occur with many known and even new conventional foods.
Genetic pollution is a term for uncontrolled [1] [2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [3] but has come to be used in some broader ways.
Genetic engineering is a laboratory process that alters the DNA make-up of an organism. This may include deleting or adding a segment of DNA. [2] Genetically Modified Organisms typically refers to food products that have been altered using genetic engineering. This is done by adding DNA to a single cell, that will later be present in the rest ...
This would involve engineering organisms that use artificial xeno nucleic acids (XNA) instead of DNA and RNA, or that have an altered or expanded genetic code. [2]: 33–36, 43, 49 These would be theoretically incapable of horizontal gene transfer to natural cells. There is speculation that these methods may have lower failure rates than ...

Advocates support the development of therapeutic cloning in order to generate tissues and whole organs to treat patients who otherwise cannot obtain transplants, to avoid the need for immunosuppressive drugs, and to stave off the effects of aging. Advocates for reproductive cloning believe that parents who cannot otherwise procreate should have ...
The He Jiankui genome editing incident is a scientific and bioethical controversy concerning the use of genome editing following its first use on humans by Chinese scientist He Jiankui, who edited the genomes of human embryos in 2018.
