Objective:

Understand the Applications of Genetic Engineering

New Words:

Transgenic Organisms, GMO (Genetically Modified Organisms)

Genetic engineering is a technique that makes it possible to transfer DNA
sequences from one organism to another


1. What is genetic engineering?


2. What are transgenic organisms?

Organisms that contain genes from other species

Examples of Transgenic organisms

Transgenic
microorganisms

Transgenic

plants

Transgenic

animals

Objective:

Understand the Applications of Genetic Engineering

New Words:

Transgenic Organisms, GMO (Genetically Modified Organisms)


They reproduce rapidly and are easy to grow


3. Why to use transgenic bacteria?


Production of insulin, growth hormone, and clotting factor


4. How do humans benefit from transgenic microorganisms?

Transgenic microorganisms

Production of


Substances to fight cancer


Plastics


Synthetic fibers

5. What do we expect to achieve in the future?

Objective:

Understand the Applications of Genetic Engineering

New Words:

How to Transform Bacteria?


4. The recombinant plasmid
replicates

and a large
number of identical bacteria
are
cloned
. They produce
human
insulin
.

2. Remove a
plasmid

from a bacterium
and treated with the same
restriction enzymes
.

3. Bind the
plasmid

with the
human gene to form a
recombinant plasmid. Then
the
recombinant plasmid

is re
-
inserted back into the
bacterium

1. Remove the
DNA

from a human body cell,
then isolate the
human gene

of insulin using
restriction enzymes
.

Objective:

Understand How to Transform Bacteria

7. How do humans benefit from transgenic plants?



Increase crop productivity



Corps able to resist weed
-
killing chemicals


Crops that produce a natural insecticide, not need to spray pesticides

6. What are transgenic plants?

Plants that contain genes from other species

Transgenic Plants

Transgenic Corn

Golden rice is a variety of rice produce through genetic engineering to include vitamin
in the edible parts of rice.





Golden rice was developed as a fortified food to be used in areas where there is a
shortage of dietary vitamin A.




No variety is currently available for human consumption. Although golden rice was
developed as a humanitarian tool, it has met with significant opposition from
environmental and anti
-
globalization activists

8. What are transgenic animals?

Animals that contain genes from other species


9. How do humans benefit?



Increase meat productivity



Livestock with extra copies of growth hormone
genes to grow faster and produce leaner meat




Transgenic chickens resistant to bacterial
infections
