Genetically Modified Organisms (GMO)
Genetically Modified Organisms are living things that have modified through biotechnology. Many fish at the pet store have been modified to have brighter more vibrant colors. Some roses have been modified to produce blue blooms. Mosquitoes that are resistant to malaria have been created in labs. While GMOs have proven to be helpful in many ways, there are safety concerns due to the lack of regulation.

What is a good analogy for GMOs?
It's like advertising to you andselling you a Chevy Corvette without telling you that the Corvette has a Chevy Spark engine in it. It may look like a Corvette, but it most certainly isn't a Corvette without the same guts.
What are the potential risk of GMO?
- The spread of transgenic crops threatens crop genetic diversity by simplifying cropping systems and promoting genetic erosion;
- HRC volunteers become weeds in subsequent crops;
- Vector-mediated horizontal gene transfer and recombination to create new pathogenic bacteria;
- Vector recombination to generate new virulent strains of virus, especially in transgenic plants engineered for viral resistance with viral genes;
- Insect pests will quickly develop resistance to crops with Bt toxin;
- Massive use of Bt toxin in crops can unleash potential negative interactions affecting ecological processes and non-target organisms.
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 cloning
- an organism
The 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.
Who is responsible for the safety of GMO's and GM products?
There is evidence that eating GMO foods has a negative effect on human and animal health. Some concerns are that they cause immune system and organ failure, Chron's disease, allergies, asthma, and infertility. Some studies have linked GMOs to cancer, though those studies have been questioned.
The process used in genetic engineering may cause unpredicted changes to the DNA that result in harmful effects.

What are the advantages and disadvantages of genetically modified organisms?
Genetically engineered organisms such as crops are given traits such as bigger seeds or better resistance to pests. This helps farmers able to produce more crops, which in turn helps feed more people. With animals, they might give it genes to grow fatter or produce more milk.
GMOs can be found in crops, such as corn, soybeans, cotton, canola, papayas, wheat, acorn squash, Golden rice, and others; medicines, such as insulin; organic crops that have been contaminated by GMO crops, foods that include GMO ingredients, dog and other pet foods made with GMO ingredients, etc.
Geographically, GMOs can be found in at least 85% of the corn and soyboans grown in the United States, crops in Canada, and crops in other countries that allow use of GMO crops.
Can genetically modified foods help people?
some people think forced sterilization will solve the overpopulation issues but china had had the one child per family rule a long time and they still are the most populated country. I don't think that is the solution. However, as more and more bacteria become drug resistant we are going to see a drop in life span by 2040 that will resemble the pre-antibiotic age with death rates at 35 years old. So polulation existence will be the problem not control. Joymaker rn
Is an organically grown crop really organic if seed is GMO or not from organic crop?
No. The National Organic Program guidelines prohibit use of GMO seeds for crops labeled "organic". GMO crops can't be sold as organic produce.
However, if a crop is grown without synthetic fertilizers, pesticides, fungicides, or herbicides, it's "organic", it just can't be labeled or sold as organic.
What happens after genetically modified plasmids inserted into bacteria?
Plasmids are cloned and start producing protein .
A non-GMO is an organism that has not been altered in a lab with a gene from an unrelated organism, such as corn that has been altered with a gene from a bacteria.
What is the debate about GMO's?
against - could release herbicide resistance into wild strains, messing with genes in innately evil, people are scared, there could be unforeseen consequences.
for- It's a good idea, less pesticides etc in the environment, more food, cheeper food, food in hostile environments, feed the hungry and the poor. climate change makes it nessesery. little chance something very bad will happen, benefits outweigh the costs.
I just wrote an article that talks about GMOs. The GMO rice, called golden rice, is described under the section "GMOs Can Improve Nutrition."
It is a social movement advocating improving human's traits to create a more optimal generation of people.
What does a GMO label look like?
A GMO label typically features the words "Genetically Modified Organism," "Contains GMOs," or "Bioengineered" prominently on the packaging. The design can vary by brand and regulatory requirements, but it often includes a symbol or logo indicating the presence of genetically modified ingredients. In some regions, such as the U.S., labeling is less standardized, so consumers may encounter different formats and styles depending on the manufacturer. Overall, the label aims to inform consumers about the genetic modification status of the product.
How many cotton farmers in India have committed suicide after crop failure of GMO cotton seeds?
Official sources put the number between 5,000 and 8,000, but some sources say it may be as high as 16,000 per year. See the related link below.
Added:
Actually, suicides of farmers were far in advance of cotton growing in India and GM crops are not a particular reason for these suicides.
The truth here is an easy Google or wiki find.
What does GMO in Oldsmobile Cutlass mean?
GMO in the context of the Oldsmobile Cutlass typically refers to "General Motors Oldsmobile," indicating the brand and manufacturer of the vehicle. The Cutlass was a popular model produced by Oldsmobile, a division of General Motors. The term itself is not an official designation but rather an abbreviation that may be used informally to refer to the model within the GM family.
