What is a transgenic organism.?
An organism with DNA from another organism.
Why do some people prefer to eat foods that are not genetically engineered?
People have genetically modified foods to make them more insect-repellant, to give higher crop yields, to give products with more appealing qualities (flavour, texture, shelf life); this provides benefits for both producer and consumer. Some crop have been modified to be resistant to certain brands of herbicides, so that the plants are not affected when the farmer sprays the area for weeds (see the Monsanto website). Other modifications take the form of plants that are modified to be resistant to saline soils, or drought conditions. These benefits can increase the yields of crops in poorer or arid parts of the world which are normally susceptible to food shortages.
A clone is an organism that is?
genetically identical to another organism. but it has no family. that is way it is illegal to clone humans.
Genes from one organism are transferred into the DNA of another organism?
An organism that is produced through genetic engineering is considered to be a genetically modified organism (GMO). Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994. Genetic engineering is also called genetic modification. While there is a worry among the public that eating genetically modified food may be harmful but scientific agreement is that these crops are no greater risk to human health than conventional food. " The transgenic products under testing seem to be safe in terms of allergenic potential. We propose post market testing as an important screening strategy for putative allergic sensitization to proteins introduced in transgenic plants."

How are plasmids used in biotechnology?
A plasmid is a circular, double-stranded DNA molecule, extrachromosomal genetic material from bacteria that usually confers some advantages to the host organism such as resistance to antibiotics, productions of colicins, etc. One important characteristic is that plasmids can replicate independently of the bacterial chromosome and therefore this aspect is extremely important to use it as tool in recombinant DNA technology. Moreover, plasmids can be cut, opening their ring configuration and inserting new genetic sequences or genes to move them from one organism to another or to obtain a particular protein through their expression in the genetically modified organism.
What is GMO in foods?
A GMO food is one that has been genetically modified by removing a gene from one species and forcing it into the seeds of another species in a lab.
What are the names of some documentary films about genetically modified foods?
One of the most known documentary on genetically modified food is Panacea or Poison. Another film that is more of an "internet sensation" than an actual film is "Controlling Our Food".
What role does technology play in genetically modified food?
Without technology, there would be no genetically modified foods, because the technology to remove a gene or genes from one species and insert it into another to produce a desired trait would not be available.
How do Schneider and Schneider define genetically modified foods?
They explain what a genetically modified food is this way: "A genetically modified (GM) food or genetically modified organism (GMO) results from the use of recombinant DNA biotechnological procedures that allow the genetic makeup of a food or organism to be altered in some way. This 'recombination' can be accomplished by moving genes from one organism to another or by changing genes in an organism that are already present. These changes result in the expression of attributes not found in the original organism."
What happens when a genetically modified animal reproduces?
the organism of the geneticaaly modified food (or GMF) will spread apart fom the female and will land on another animal and it will make it .thats how.
What is meaning of bt corn?
BT corn means that the corn has been genetically modified with DNA from another organism.
How are foods genetically modified?
Generally, foods are genetically modified by taking a gene from one species and forcing into the cells of another species in a lab to produce a desired trait. This differs from hybridization in that it is transgenic (between species) and the gene is physically forced into the cells.
What is genetically modified food and how is this process achieved?
Genetically modified foods are those that have been genetically engineered to insert a gene from one species (often a bacteria) into another species (corn, soy, etc). This is accomplished by cutting a target gene that will produce a desired trait from one species and artificially inserting it into the target plant.
Where is genetically modified food created?
Genetically modified food is created in a lab by taking a gene from one species and inserting into another species to create a desired result. Geographically, they are created in many countries throughout the world. Many are created by United States' companies, such as Monsanto.
What is transgenic technology?
Transgenic plants are plants in which DNA from another species has been introduced into the plant's genome.
What are drugs in genetically modified food?
Except for the rBGH hormone used in animals raised for food, genetically engineered food does not actually contain drugs. Genetically modified foods involve extracting a gene from one species (often a bacteria) and inserting it into another species (often corn or soybeans) in order to bring about a desired trait. This process is also used to develop new drugs
What caused genetically modified foods to happen?
Genetically modified foods happened because man discovered that a gene could be removed from one species and forced into the cells of another species to bring about a desired trait in the host, or that a gene could be removed from an organism, modified in some way, and inserted back into the same organism. In the most common genetically modified foods today (2015), the desired trait is either resistance to a herbicide or to produce an insecticide in the plant itself, although there are some other, less common traits produced through genetic modification.
