Discuss the benefits of genetically modified organisms to society.
bacteria, plants, and animals are genetically engineered to produce products.
There are many uses for genetically modifiedbacteria.
Human growth hormone is one of the products frombacteria.
There are many uses for transgenicbacteria.
Some have been made to promote the health of plants.
The frost-plusbacteria that normally live on plants have been changed to frost-minusbacteria.
New crops, such as frost-resistant strawberries, are being developed.
The roots are protected from insects.
The ability ofbacteria to degrade a particular substance can be enhanced by bioengineering.
After oil spills, naturally occurring bacteria that eat oil have been genetically engineered to clean up beaches.
Sulfur can be removed from coal before it is burned.
One strain was given genes that allowed it to clean up toxins that would have killed other strains.
When the job had been accomplished, thesebacteria were given "suicide" genes that made them self-destruct.
Researchers such as Dr. Chakrabarty have engineered and patented the ability ofbacteria to decomposing oil.
The synthesis of organic chemicals can be done by using catalysts or usingbacteria.
It is possible to manipulate the genes that code for these enzymes.
Various otherbacteria could be genetically engineered to produce phenylalanine after they isolated, altered, and formed a vector for the appropriate genes.
The protoplasts are suspended in a liquid and treated with an electric current.
Through the holes created by the current, the DNA can enter.
The treated protoplasts grow into mature plants.
Foreign genes have made cotton, corn, potato, and even bananas resistant to pests because their cells now produce a chemical that is toxic to pests.
Similarly, soybeans have been made resistant to a weed killer.
Corn and cotton plants are resistant to pests.
Golden Rice has been engineered to have a higher level of vitamins A and C.
Improvements that reduce waste from food spoilage are some of the improvements that have been made with genetic engineering in plants.
A company called Okanagan Specialty Fruits knocked out a gene that causes apples to brown and created a genetically modified apple with an increased shelf life.
The goal of these and other genetically modified crops is to increase yields and improve nutrition.
Plants are being engineered to produce human proteins, such as hormones and clotting factors, in their seeds.
One type of antibody made from corn can be used to deliver radioisotopes to tumors and another can be used to treat genital herpes.
Tobacco plants are being used to develop a vaccine.
The eggs of animals have genes inserted into them.
It is possible to microinject foreign genes into eggs by hand.
The eggs are placed in an agitator with needles that make small holes for the DNA to enter.
Transgenic animals are offspring of fertilized eggs.
Many types of animal eggs have taken up the bGH gene through this technique.
The procedure has been used to produce larger animals.
The genes that code for the diagnostic and therapeutic genes are found in the animal's milk.
Drugs have been developed using this process.
zygotes are placed in host females where they develop.
The product is in the milk of the female offspring.
The West Coast of the United States is home to the crystal jelly.
The green color of the aequorin is caused by the transparent nature of the jellyfish.
The scientists were able to develop a tag for the fluorescent protein from the jellyfish.
The promoter of that gene is the subject of a binding action by the polymerase.
These tags can be generated for almost anyprotein within the cell, revealing not only its cellular location but also how its distribution within the cell may change as a result of a response to its environment.
They are available for purchase as pets.
Actin is part of the cell's microfilaments, which are part of the cell's cytoskeleton.
The distribution of actin is shown in the image.
Discuss how a researcher can use GFP to study cancer.
