genetically modified animals

The Authority has also developed a guidance document on the environmental risk assessment (ERA) of GM animals, which covers GM fish, insects, mammals and birds. Salmon, for example, has been genetically engineered to mature faster, and the U.S. Food and Drug Administration has stated that these fish are safe to eat. However, scientific developments suggest submissions may be made in future across a range of species. With animals DNA is generally inserted into using microinjection, where it can be injected through the cell's nuclear envelope directly into the nucleus, or through the use of viral vectors. This fish is actually able to grow twice as fast as typical fish, despite having the same odor, color, texture, and flavor of standard salmon. EFSA concluded that a risk assessment of GM animals should include three major aspects. This gene means that the baby mosquitoes would die (naturally of old age) before reaching sexual maturity. [82] Treatments are also being developed for a range of other currently incurable diseases, such as cystic fibrosis,[83] sickle cell anemia,[84] Parkinson's disease,[85][86] cancer,[87][88][89] diabetes,[90] heart disease[91] and muscular dystrophy. People with such skin would survive more and would have more successful babies. [50] Modifications have also improved the wool production of sheep and udder health of cows. Pigs have been genetically modified so that their organs can no longer carry retroviruses[43] or have modifications to reduce the chance of rejection. • To do this artificially may require attaching the genes to a virus or … • When genes are inserted, they usually come from a different species, which is a form of horizontal gene transfer. The basic assumption of this type of comparative assessment is that food and feed from conventionally-bred animals have a history of safe use and therefore can serve as a baseline for the risk assessment of food and feed derived from GM animals. Other terms … The gene responsible for Albinism in sea cucumbers has been found and used to engineer white sea cucumbers, a rare delicacy. [37] In 2009, scientists announced that they had successfully transferred a gene into a primate species (marmosets) and produced a stable line of breeding transgenic primates for the first time. Genetically modified organisms (GMOs) are produced using scientific methods that include recombinant DNA technology and reproductive cloning. Transgenes can also be combined with RNAi to rescue phenotypes, altered to study gene function, imaged in real time as the cells develop or used to control expression for different tissues or developmental stages. [55] This caused the pigs to produce the enzyme phytase, which breaks down the indigestible phosphorus, in their saliva. The first transgenic livestock were produced in 1985[28] and the first animal to synthesise transgenic proteins in their milk were mice,[29] engineered to produce human tissue plasminogen activator in 1987. The genetic modification is an RNA molecule that prevents the virus reproduction by mimicking the region of the flu virus genome that controls replication. Based on the wide range of GM research being conducted on different animal species, the European Commission requested that EFSA develop environmental risk assessment guidance for GM fish, insects, mammals and birds. [128][129][127] Another approach is to use the sterile insect technique, whereby males genetically engineered to be sterile out compete viable males, to reduce population numbers. Proc. For example, soybeans have been modified to resist an herbicide called Roundup. EFSA’s role is to independently assess and provide scientific advice to risk managers on any possible risks of GMOs for human and animal health and the environment and to propose appropriate measures to mitigate the risks.
