Gene pharming is used to produce a beneficial effect when inserted into animals. This is done by altering one animal's DNA from another species. An effect of this is the production of several proteins and drugs useful to the society. Even though this is good, it is really expensive and not all the animals who undergo the experiment actually survive in the end. Pharming can also be harmful to the animals involved with the experiment. Scientists usually create these genetically engineered animals by injecting embryos into the animals' DNA.
Genetic engineering can be used to add or remove genes in the DNA. Some reasons that scientists have genetically engineered animals is because they want to research human diseases, improve the animal's health, or produce products from it. Even though these are all beneficial to the human society, the process of this experiment is very slow. However, new technologies are being used to make this process more efficient and quicker. These technologies could also increase the chance that the animal who is born has the targeted transgene.
