How are genetically modified organisms different from non-genetically modified organisms?
a transgene is a gene that is not native to an organism (eg. it is a gene that is transferred from one organism to another)
recombinant DNA is DNA that has essentially been combined with other, different DNA. DNA is double-stranded (the two strands are held together by basepair complementation). during recombination, the strands break apart, thus allowing another strand to bind with either of the original strands:
original strands
DNA you want to insert into the organism (aka. a transgene) ]]
you break apart the original strands | |
and you add your strands |] |]
now you have recombinant DNA, which is what a transgene will be when it has been integrated into an organism. it will (hopefully) be expressed correctly.
(it's sliiightly more complicated than this haha, and the transgene can integrate (recombine) in numerous ways... but that's a solid foundational understanding of the process)
hope this helps!

CoachGenetically modified organisms (GMO) are different from non-genetically modified organisms in that GMO have had their genes manipulated and intentionally changed by human action in a laboratory. With GMO we can introduce any particular character by providing gene sequence responsible for that character

What is GMO genetically modified organisms?
A genetically modified organism results from a gene being removed from one organism and artificially inserted into an organism of a totally different species. This is a simplified explanation and the process is done in a lab.
How many food companies use genetically modified organisms in their products?
Nearly every company uses "genetically modified organisms" in their products, because nearly everything we raise for food today has been bred so that it's quite different from its wild ancestors ... its genetics have been modified.
Who discovered genetically modified organisms and when?
No one discovered genetically modified organisms. Such organisms are created by people working in laboratories. In 1953 it was discovered that DNA is the material that carries genes, the information that defines and structures each organism. For the next 50 years people worked to understand DNA and eventually learned how to modify it, in some circumstances. When such a modification is successful, the result is an organism that has been genetically modified - a genetically modified organism.
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.
