Human germline engineering (HGE) is the process by which the genome of an individual is modified in such a way that the change is heritable. This is achieved by altering the genes of the germ cells, which mature into eggs and sperm. For safety, ethical, and social reasons, the scientific community and the public have concluded that germline ...
However, He's human experiments raised ethical concerns the effect are unknown on future generations. [112] Ethical concerns have been raised relative to the four ethical criteria of autonomy, justice, beneficence, and non-maleficence, [114] [113] first postulated by Tom Beauchamp and James Childress in Principles of Biomedical Ethics.

The first genetically modified animal was a mouse created in 1974 by Rudolf Jaenisch. In 1976, the technology was commercialised, with the advent of genetically modified bacteria that produced somatostatin, followed by insulin in 1978. In 1983, an antibiotic resistant gene was inserted into tobacco, leading to the first genetically engineered ...
The first company to focus on genetic engineering, Genentech, was founded in 1976 and started the production of human proteins. Genetically engineered human insulin was produced in 1978 and insulin-producing bacteria were commercialised in 1982. Genetically modified food has been sold since 1994, with the release of the Flavr Savr tomato. The ...
In bioethics, the ethics of cloning concerns the ethical positions on the practice and possibilities of cloning, especially of humans. While many of these views are religious in origin, some of the questions raised are faced by secular perspectives as well. Perspectives on human cloning are theoretical, as human therapeutic and reproductive ...
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination".

The first successful pig kidney transplant in a living recipient — a milestone in the field of so-called xenotransplantation, or animal-to-human transplant — could offer hope to the tens of ...
The different generations of nucleases used for genome editing and the DNA repair pathways used to modify target DNA. Genome editing, or genome engineering, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism.
