Deck 7-Slides 28-34 Flashcards
Genetic engineering makes it possible to transfer _______ from one organism to another.
Genes
In 1986, Steven Howell isolates the gene for ________ (allows fireflies to glow) and inserted it into a tobacco cell.
Luciferase
Tobacco plant grew from the cell and the plants ________ in the dark.
Glowed
Steven Howell’s experiment shows that the basic mechanisms of gene expression are _______ by plants and animals.
Shared
Transgenic organisms contain ________ from other species.
Genes
In transgenic organisms, a foreign gene is inserted into _____ fell, and an organism is then ________ from that cell.
One, grown
Genetic engineering spurred the growth of _____________.
Biotechnology
Biotechnology is a new industry that is changing the way we _________ with the living world.
Interact
Because they reproduce rapidly and are easy to grow, __________ __________ now produce a host of important substances useful for health and industry.
Transgenic bacteria
Examples of transgenic bacteria are human proteins such as ______, ________, ________ ________. Once rare and expensive, are now produced by transgenic bacteria cheaply and in great abundance.
Insulin, HGH, clotting factor
In the future, transgenic bacteria may produce substances designed to fight ________ (ex. Interferon), as well as raw materials for _________ and ________ ________.
Cancer, plastics, synthetic fibers
And example of transgenic animals are mice with human genes that make their ________ system act similarly to those of humans.
Immune
These transgenic mice allow scientists to study the effects of _________ on the human immune system.
Disease
Transgenic livestock that have extra copies of ________ ________ genes grow faster and produce more and leaner meat.
Growth hormone
Another example of transgenic animals is transgenic chickens that will the resistant to the ________ ________ that can cause food poisoning.
Bacterial infections
