Genetically-modified foods GM foods have made a big splash in the news lately. European environmental organizations and public interest groups have been actively protesting against GM foods for months.
The organism could be an animal, plant, or microorganism.
The changing of the genetic code could involve subtracting, adding, or altering. All these changes could be from the same species or different species, which would give the organism characteristics that it does not have normally.
GMO technology is widely used for scientific research and in the production of foods and goods. A GMO results from the laboratory process of extracting genes from the DNA of a species and forcing the genes into an unrelated plant or animal's genes.
The foreign genes come from viruses, bacteria, animals, insects, or even humans. GMOs allow for the production of organisms with desired biological traits or favor the expression of some desired traits. Conventional crop farming, livestock production, and pet breeding have involved the practice of select breeding in order to produce offspring's with desirable traits.
Genetic modification employs technology to produce organism that have their genomes altered in a precise manner at the molecular level.
This process involves the introduction of genes from unrelated species, which would not be possible using conventional breeding. In order to reproduce offspring with the same genetics as the parent one would use reproductive cloning technology. This involves the transfer of the entire donor's nucleus into the host egg's enucleated cytoplasm.
Dolly was the first animal to be born using this technology in Recombinant DNA technology involves inserting one or more individual genes of a particular organism into the DNA of another.
The two organisms are not necessarily from the same species. Reproductive cloning According to Bowring Reproductive cloning is the deliberate production of organisms with the same genetic as the parent.
In this case, each of the genetically produced organisms would be a clone of the original. This involves transferring the nucleus of a body cell to an egg, which has its nucleus removed.
This would produce a clonal embryo that needs electricity or chemical triggers in order for it to begin developing. Placing the cloned embryo in the uterus of a female, where it comes to term, thus creating a clone. The clone will have identical genes as those of the original animal. For implanting the cloned embryo, one can use a real or an artificial uterus.
Reproductive cloning is more difficult than it sounds. The process has a low rate of success, and in the case of the cloned sheep, the scientists confirmed that they had to try around times.
The attempts required demonstrate that this process is highly impractical. The nucleus extracted from the donor may not reproduce after it is inserted it the donor egg.
Even after the insertion, the process requires triggering in order for reproduction to occur. The egg needs to reproduce enough times for consideration as an embryo fit for implantation into a female.
The female implanted with the embryo is not necessarily the donor, and the chances that the embryo will reach its term are low. The born animal might be deformed, which renders the whole process a failure and the scientists have to start all over again.
There is significant progress in reproductive cloning, but scientists have had trouble trying to clone dogs and monkeys. They have faced numerous challenges like getting a female to carry the embryo and growing the embryo without losing chromosomes. These challenges make the use reproductive cloning a less viable means of GMO production.Vu 1 Chau Vu Mrs.
Ogo APES, Period 1 4 April The use of labeling for GM products Nowadays, along with the development of biotechnology, there are many inventions to improve to quality of our food including Genetically Modified Food (GM’s food).
Consider writing about genetically modified food pros and cons. Genetically modified foods (also known as genetically modified organisms, or GMO) and the labeling of foods that are genetically modified is a contentious debate.
When products are labelled for Genetically Modified Organisms, individuals will manage to choose whether they want to consume them or not. In this regard, failure to label products . Aug 25, · Why Liberal Americans Are Turning Against GMO Labeling.
state to require any genetically modified foods to carry a label, although it is being challenged in court.
based natural products. Genetically modified organisms (GMOs) can be defined as organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally. The technology is often called "modern biotechnology" or "gene technology", sometimes also "recombinant .
Genetically modified organisms (GMOs), also known as genetically modified or engineered foods, are created by forcing a piece of DNA from a totally different species, such as bacteria or viruses, into the DNA of a plant or animal.
