Why are genetically modified organism beneficial?
Genetically modified organisms are modified on a genetic level to benefit humans. How this can pose a threat to a population or ecosystem, is that if the genetically modified organism were to somehow create a mutation, and pass that on, it could be damaging to the future generations in reducing their health or other issues may arise. It can also be damaging to an ecosystem if a genetically modified organism were to escape into a wild population and change it.
How can GMOs affect allergies in people or animals?
GMOs (genetically modified food) may create allergies.
What is the process of making a genetically modified organism in a lab?
Contrary to the common understanding of the word, the process which we use to create transgenic organisms is called "cloning". This doesn't refer to copying an organism as often believed. Cloning as scientists mean it refers to creating DNA which does not naturally occur in any organisms. This is also called transgenic DNA.To make a genetically modified organism, we need:transgenic DNA - made by cloningan organismThe transgenic DNA of course needs to be made for a specific purpose. Depending on how big it needs to be, it can be made in different ways. Very small stretches of DNA can be synthesised chemically. Larger bits of DNA are usually made by extracting a cell's DNA and then using a technique called polymerase chain reaction (PCR) to take only one particular bit of the DNA out. We then use restriction enzymes and ligase to cut and paste different bits of DNA together. Usually, the end product will be a plasmid.The finished plasmid (transgenic DNA) then needs to be introduced into the target organism - and there are different ways of doing it for every type of organisms. Some bacteria for example will simply take up plasmids and integrate them into their own DNA without a complicated process around it being necessary. For bigger organisms like animals, it's very difficult - usually impossible - to modify an already living organism. For these, the only option is usually to take an oocyte (egg cell, e.g. a flower seed) and introduce the plasmid into it. If the egg survives this procedure and develops (which is very difficult to achieve), the resulting organism will be transgenic, or genetically modified.
What are the advantages of GMO plants?
enetically modified foods or biotech foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise[1] than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding; plant breeding, and animal breeding, and somaclonal variation. Since genetically modified food has been introduced into supermarkets, there has been much controversy as to whether it is actually safe.
How has the application of a scientific discovery helped create new technology?
It has given scientists ideas.
What is the name of the process through which scientists create genetically identical organisms?
Cloning

Why do scientists create genetically modified crops?
Genetically modified crops are made in order to make a desired trait, such as high yield, disease resistance, large fruit etc. more pronounced and/or undesired traits, such as toxins and large seeds...
What is the use of bacteria and other microoganisims to change pollutants in soil and water into harmless chemicals?
Scientists believe that bacteria and other micro organisms can be genetically modified to help clean up the environment. Humans create a huge amount of waste material as a result of their existence. This waste material is in such large quantities that it would take nature literally thousands of years to degrade it. Some waste materials cannot be naturally degraded. Several years ago, scientists created a genetically modified bacterium that could clean up oil spills and turn them into metabolites that were less harmful to aquatic creatures. This incredible use of technology propelled researchers to find solutions to other environmental problems and create genetically modified organisms that could help clean up the waste created by humans
How are chickens genetically modified?
Both. Big Corporations like Tyson are getting scientists to genetically create chickens with larger breasts (for more versatile use in fast food). Selective breeding is still the preferred way to increase quality and productivity.
How can GMOs affect allergies in people or animals?
GMOs (genetically modified food) may create allergies.
What is genetic modified foods?
Genetically modified food can also be achieved by altering their DNA (or genes) by genetic engineering techniques. This usually involves inserting a gene into the organisms' DNA to create a certain trait. For example, some corn crops have been genetically modified so that they become more resistant to herbicides and insect pests. In most countries Genetically Modified foods (GM) as well as foods containing GM source foods have to be labelled by law, giving consumers the choice to use them or not. Agriculturally speaking the opposite of GM foods are "Organic" crops.
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.
How did Stanley Cohen and herbert boyer create the first genetically altered organisms?
they were very smart and they knew what they were doing
What is the importance of transgenic organisms?
A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known as recombinant DNA technology, use DNA molecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes. Transgenic organisms, a subset of GMOs, are organisms which have inserted DNA that originated in a different species
Genetic engineering may enable scientists to?
Genetic engineering may enable scientists to create micro-organisms, animals and plants. These are commonly referred to as clones of the originals.
When scientists use cells to produce an identical creature it is known as what?
Mitosis is the process whereby a cell replicates its DNA and divides into two identical daughter cells. Meiosis produces genetically unique haploid sex cells.
