Because genes are so universally similar, it is possible to transfer genes from one organism to another. Organisms produced by such a process are called genetically modified organisms or transgenic organisms. The term genetically modified organisms refer to not only plants and animals, but also bacteria. Transgenic organisms are created by gene insertion, gene deletion, or gene replication. In a normal gene, gene replacement results in only the implanted gene being active. Gene insertion results in no active gene being present. And gene insertion results in both the normal and transplanted gene being active. A foreign or modified gene is called a transgene. In making transgenic plants, scientists usually use modified Agrobacterium to insert the transgene, or inject DNA directly into a plant cell. In the making of transgenic animals, scientists often insert the transgene directly into the animal’s egg cell, due to animal cells being relatively large. Once the transgenes enter an organism, enzymes that normally repair DNA, helps insert the new DNA fragment into the organism’s genes. One example of a transgenic organism is the C5 plum. The C5 has been engineered to have resistance to a specific virus known as Plum Pox or Sharka. The virus affects the entire plant and causes it to produce a decreased amount of fruit, and most of the fruit produced are deformed. To create a plant that was resistant to Sharka, scientists collected the genes for the virus protein coat, which…
3 main organisms that are genetically modified.
Method of organization: Topical
A. Hook- The year is 1982, scientists Ralph Brinster and Richard Palmiter were in their lab and curious if anything would happen by inserting a human growth hormone into an animal. They experimented this idea by using a mouse. The results of that experiment? The Supermouse was created. The Supermouse was over twice as big as the parents. Now the year is 2015 and research for transgenic organisms have advanced…
achieve desired results. Genetic engineering is used to produce transgenic organisms, which are organism’s whose genetic makeup has been modified to change the organism for the better or worse. This topic includes transgenic microorganisms, which are mutated bacteria; transgenic plants, which are an important part of our food supply, and transgenic animals, which are used to study genes and used to improve food supply and quality.
Transgenic microorganisms are, as the name suggests, microorganisms like…
What is the connection between what the Wyatt Transgenics Company does and the reference to the comic “The Swamp Thing”?
The connection between Wyatt Transgenics and the comic is that in the company they alter organism’s genes and the swamp thing had its genes altered.
What does the term “transgenic” mean?
Transgenic is when an organism is altered by having a gene from another species transferred into the original organism
How do the scientists make the animals develop the desired proteins? How…
Genetically Modified Organisms (GMOs)
For a very long time humans have tried to modify the agricultural and live stock production by selecting certain characteristics or properties of plants and animals with the objective of improving their production. But before all this men used conventional breeding methods such as selection and crossbreeding in order to improve performance, product quality and adaptability to natural conditions. “Today there are breeding programs which have come a long way…
GMOs, Helpful of Harmful?
Genetically modified organisms, also known as GMOs, make up for majority of the foods being produced today. There are a few to no benefits to these altered and ‘fake’ organisms. GMOs are organisms that have had their gene material altered by a process called genetic engineering. Many serious effects occur to the environment on which they are grown, and to those who consume these ‘alien’ foods. The affects of GMOs may be large or small, in any case, but there are…
the fundaments of genetics, those organisms were submitted to rational genetic improvement mainly by selecting of traits
of interest. Breeders used appropriate gene combinations to produce new animal races, plant varieties and hybrids, as well as
improved microorganisms such as yeasts. After the introduction of recombinant DNA techniques, the transfer of DNA between
species belonging to different genera, families or kingdoms became possible. The release of transgenic plants has aroused
encounter products of recombinant DNA on a daily basis. The process involves the manual combination of genetic information from several different sources; ultimately creating an entirely separate organism with a set of genetic information that was otherwise not biologically probable. Molecules of all living organisms possess mutual chemical structures, making this method feasible. The difference lies within an organism’s unique nucleotide sequence.
With great science comes great controversy. Although…
their benefits and their problems. I think that cloning is good because it can help with many medical advances and food production.
Cloning is the creation of an organism that is an exact genetic copy of another. It is the process of producing similar populations of genetically identical individuals that occur in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning is used to create an exact copy of a mammal by using the complete genetic material of a regular body…
Greater production of food especially for developing countries would allow
these countries to produce enough food for their population.
