  1. Living modified organism

    LMO stands for living modified organisms , which are those organisms that have been genetically modified through the application of biotechnology including organisms that have been modified by novel recombinant DNA techniques as well as those that have been modified by mutagenesis or classical breeding and selection techniques. Genes are not invented but LMOs are patentable because they are covered by DNA patents viewed as created by human endeavour rather than nature. The first and most famous LMO case that set the precedent was Diamond v. Chakrabarty . In 1971 Professor Ananda Mohan Chakrabarty , then a scientist for General Electric , created a genetically modified microorganism that ate hazardous waste. General Electric then went to the United States patent office claiming they had invented this bacteria and needed a patent the first patent on a Genetically modified organism genetically engineered organism . The Patent Office immediately turned down the request citing a living organism cannot be patented. In 1980 the U.S Supreme Court ruled in favor of Chakrabarty General Electric. The Supreme Court finding in favor of artificial products over natural products in the Chakrabarthy case was the basis of the 1988 patent grant for the Harvard mouse or Oncomouse OncoMouse developed as a cancer research tool. ref Travels in the Genetically Modified Zone ref The rights to the invention are owned by DuPont .

  1. Traceability of genetically modified organisms

    The traceability of Genetically modified organism genetically modified organisms GMOs describes a system that ensures the forwarding of the identity of a GMO from its production to its final buyer. Traceability is an essential prerequisite for the Co existence of genetically modified and conventional crops and derived food and feed co existence of GM and non GM foods, and for the freedom of choice for consumers. Why traceability is needed The traceability of GMOs is founded on two needs. First, consumers in many countries are reluctant to buy genetically modified foods, and are sceptical of the use of GM crops for animal feed. Consequently, the concept of co existence has been developed to separate GM and non GM supply chains, and is only possible if all purchasers along the production chain know what they are buying. Secondly, although every GMO that is approved for commercialisation must have passed a safety assessment, it may be necessary to withdraw a certain GMO from the market for example, if new scientific evidence raises doubts about its safety. Unique identifiers for GMOs For these purposes, after three years of debate, the OECD countries came up with an identity code for GMOs ... on the labelling and traceability of genetically modified organisms Regulation EC No 1830 2003 ... of genetically modified organisms External links http bch.biodiv.org organisms default.shtml ... of 22 September 2003 concerning the traceability and labeling of genetically modified organisms and the traceability of food and feed products produced from genetically modified organisms http www.coextra.eu ... database 997.safety research project environmental traceability genetically modified rape cultivars.html GMO Safety Environmental traceability of genetically modified rape cultivars Research ... pentland gumpert USDA Bets the Farm on Animal ID Program Category Food safety Category Genetically modified organisms in agriculture ar ...   more details

  1. Detection of genetically modified organisms

    The detection of genetically modified organisms in food or feed is possible by biochemical means. It can either be qualitative, showing which genetically modified organism GMO is present, or quantitative, measuring in which amount a certain GMO is present. Being able to detect a GMO is an important part of food safety, as without detection methods the Traceability of genetically modified organisms traceability of GMOs would rely solely on documentation. Polymerase chain reaction PCR The polymerase chain reaction PCR is a biochemistry and molecular biology technique for isolating and exponentially amplifying a fragment of DNA , via enzymatic replication, without using a living organism. It enables the detection of specific strands of DNA by making millions of copies of a target genetic sequence. The target sequence is essentially photocopied at an exponential rate, and simple visualisation techniques can make the millions of copies easy to see. The method works by pairing the targeted genetic sequence with custom designed complementary bits of DNA called Primer molecular biology primers . In the presence of the target sequence, the primers match with it and trigger a chain reaction. DNA replication enzymes use the primers as docking points and start doubling the target sequences. The process is repeated over and over again by sequential heating and cooling until doubling and redoubling has multiplied the target sequence several million fold. The millions of identical fragments are then purified in a slab of gel, dyed, and can be seen with UV light.It is not prone to contamination. Quantitative detection Quantitative PCR Q PCR is used to measure the quantity of a PCR product preferably real time, QRT PCR . ref name LoganEdwardsSaunders cite book author Logan J, Edwards K, Saunders ...

  1. Genetically modified virus

    A genetically modified virus is a virus that has gone through genetic modification for various biomedical purposes. General usage Genetic modification involves the insertion or deletion of genes. When genes are inserted, they usually come from a different species, which is a form of horizontal gene transfer . In nature this can occur when exogenous DNA penetrates the cell membrane for any reason. To do this artificially may require attaching the genes to a virus or just physically inserting the extra DNA into the nucleus of the intended host with a very small syringe, or with very small particles fired from a gene gun . ref cite journal author Johnston SA, Tang DC title Gene gun transfection of animal cells and genetic immunization journal Methods in Cell Biology volume 43 Pt A issue pages 353 365 year 1994 pmid 7823871 oclc 31189762 ref However, other methods exploit natural forms of gene transfer, such as the ability of Agrobacterium to transfer genetic material to plants, ref cite journal author Lee LY, Gelvin SB title T DNA binary vectors and systems journal Plant Physiol. volume 146 issue 2 pages 325 332 year 2008 month February pmid 18250230 pmc 2245830 doi 10.1104 pp.107.113001 ... ref Lithium ion batteries In materials science, a genetically modified virus has been used to construct ... ref uses genetically modified viruses to deliver genes that can cure disease into human cells.

  1. Isolation distance for genetically modified plants

    Unreferenced date April 2008 Isolation distances are used in regions where Genetic engineering genetically modified GM and conventional or organic crops are grown in Co existence of genetically modified and conventional crops and derived food and feed co existence . When different cropping systems are grown in proximity to each other, the isolation distance between fields refers to the area separating them, on which genetically modified pollen can settle without fertilising non GM crops. Goal of isolation distances The goal of isolation distances is to minimise out crossing of GM plants. If large amounts of GM pollen fertilise crops in a non GM field, that harvest may no longer be declared GM free , and will require appropriate labelling if its GM content exceeds a certain limit e.g. 0.9 percent in the European Union . Design of isolation distances Isolation distances are mostly empty spaces. They may be roads, uncultivated fields, or anything that separates two fields without actively hindering the drift of pollen. Separation methods between GM and non GM fields which actively catch pollen are called Pollen barrier pollen barriers or buffer zones . Factors influencing isolation distances Many factors influence the width required for isolation. A major criterion is the crop species, since isolation distances often must be calculated according to pollen weight. Other influential criteria include the size and shape of fields, GM contamination tolerance levels and, especially, local wind direction and weather conditions. Isolation distances for maize Maize is probably the best studied crop in terms of isolation distances. Yet, recommendations for isolation distances have varied significantly. Under average conditions, the isolation distance may be 25 metres. However, in regions with small non GM fields 1 hectare , or with crops being grown primarily for seed production, the isolation distance may be more than 100 metres. Research on isolation distances Among dozens of individual ...   more details
