Genetically Modified Organisms - Animals, Crops & Applications

In transgenic studies, a promoter is a regulatory DNA sequence that initiates transcription of a particular gene, thus determining where and to what extent the transgene is expressed in the target tissue.

Matching the transgenic plants to their respective resistances: Papaya is engineered for resistance to ring spot virus (A-II). Bt cotton is engineered for resistance to insects (B-IV). Roundup ready soybean is resistant to glyphosate herbicides (C-I). Tomato has been modified for delayed ripening or other traits like resistance to Pseudomonas (D-V). Thus, the correct pairing is A-II, B-IV, C-I, D-V.

Genetically modified bacteria were the first organisms to be modified in the laboratory, due to their simple genetics. These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine. The drug industry has made use of this discovery in its quest to produce medication for diabetes. 

Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics.They are identified as a class of genetically modified organisms. Transgenic plants can be created by inserting genes of other organisms. 

The 'Giant Mouse' (super mouse) was created by introducing the rat growth hormone gene into the mouse genome, which is a classic example of gene manipulation (transgenesis).

Pseudomonas putida is a gram-negative bacteria that helps in cleaning the oil spills.

Bioremediation is the process of treating the contaminated water, soil and subsurface material by altering the environmental conditions in which the growth of microorganisms is stimulated.

Transgenic mice are widely used as models to test the safety of vaccines, such as the polio vaccine, before they are administered to humans, reducing the need for using monkeys.

Pseudomonas putida is a well-known genetically engineered microorganism used in bioremediation to break down hydrocarbons in oil spills.

Mice are the most common model organism used in genetic engineering research due to their short generation time, ease of handling, and physiological similarity to humans.

Recombinant DNA technology is the fundamental technique that allows scientists to cut, join, and insert DNA from one organism into another, enabling genetic engineering.

Pigs are often researched as potential organ donors for humans (xenotransplantation) because their organ sizes are similar to humans, and they can be genetically modified to reduce immune rejection.

Transgenic animals are created to study diseases, test safety, and produce proteins, not to stimulate or create new pathogens.

Transgenic mice are specifically designed to be sensitive to certain pathogens or toxins, making them excellent models for testing the safety and efficacy of vaccines.

Using E. coli to produce insulin allows for large-scale, cost-effective, and unlimited production of human insulin, which is safer than insulin derived from animal pancreases.

Transgenic Organism or Genetically Modified Organisms (GMO) is an organism whose genetic material has been altered using genetic engineering techniques. Bacteria are the easiest organism to engineer and have been used for research, food production, industrial protein purification etc. There is a potential to use them for environmental purposes or as medicines.

There are various genes that are found in animals and pants that are of important use for the humans. These genes are extracted and then introduced into organisms by genetic engineering.
