SEQUENCE THE STEPS IN MAKING A GENETICALLY ENGINEERED ORGANISM

2. Genetic Engineering
Through genetic engineering, scientists are experimenting with biological and chemical methods to change the arrangement of DNA that makes up a gene.
Genetic engineering already is used to help produce large volumes of medicine.

3. Recombinant DNA
Recombinant DNA is made by inserting a useful segment of DNA from one organism into a bacterium.
This method is used to produce human insulin, human growth hormone, and other chemicals by bacteria.

4. Gene Therapy In gene therapy, a normal allele is placed in a virus.
The virus then delivers the normal allele when it infects its target cell.
The normal allele replaces the defective one.
Scientists are conducting experiments that use this method to test ways of controlling cystic fibrosis and some kinds of cancer.
Gene therapy might be a method of curing several other genetic disorders in the future.

5. Selecting plants or animals with the most desired traits to breed for the next generation is called selective breeding.
Genetic engineering can produce improvements in crop plants, such as corn, wheat, and rice.
One type of genetic engineering involves finding the genes that produce desired traits in one plant and then inserting those genes into a different plant.
