Download 13-4 Applications of Genetic Engineering

Chapter 13:Genetic Engineering (13-4)
Genes from other organisms can work together and
still function (ex. luciferase and tobacco plants)
 Transgenic—contain genes from other organisms
 A gene from one organism can be inserted into cells
from another organism.
 Genetic engineering has spurred the growth of
biotechnology, a new industry that is changing the
way we interact with the living world.

Bacteria—insulin, growth hormone, clotting factors,
interferon.
Future??? Substances to fight cancer, or make
materials, synthetic fibers
Study genes, improve food supply
Transgenic livestock—extra copies of growth
hormone genes (grow faster, less fat)

Future??? Disease/bacteria resistant
chickens….and, animals that can produce human
proteins in their milk.
Year 2000, 52% of soybeans, and 25% of corn
grown in the U.S. were transgenic of genetically
modified.
Produce natural insecticide (no spraying)
Plants/foods resistant to rot
Rice plants that add vitamin A, major food to
billions.
Clone- members of a population of genetically
identical cells produced from a single cell.
 Cloned colonies of bacterial cells are easy to
grow…this is not true for multicellular organisms.
 Ian Wilmut’s technique produced such a clone
(Dolly)…see page 332-333 (figure 13-13)
