Aim: What are some other
applications of genetically
engineered organisms?
LO: SWBAT explain some
applications of genetic
engineering
DN: Describe what a transgenic
organisms is, and identify how
transgenic bacteria have been
used to benefit humans.
HW: page 330- read and
complete research and decide
What is a Genetically Modified
Organism (GMO)?
Is any organism that has acquired one
or more genes
______ by artificial means.
A GMO is said to be
transgenic
This means that the
GMO containsDNA
from different
species.
What are the benefits to genetically
modified plants and animals?
1)To make pesticide __________
resistant plants.
2)GM plants can produce natural
__________.
pesticide
vitamin content.
1)To increase ________
2)To make food last _______.
longer
3)Getting food to the market _______.
faster
Some Examples of GM Plants:
Golden Rice is genetically
modified so it contains ______
genes
_________
from daffodils to _________
increase the
production of ______________
beta-carotene
(an important precursor of Vitamin A).
Scientists have also genetically
_________
modified sweet corn
so it contains genes
_____ from a bacteria
that allow the corn to produce a natural
__________.
pesticide
How do scientists genetically
modify plants?
Example of a GM Animal:
These two salmon
are the same age,
but the GM salmon
grew at about twice
the rate.
**It is more difficult to genetically
modify animals than
plants.
What are the risks of GMOs?
1)Increase in food
________.
toxicity
2)The creation of new
__________.
allergens
3) Reduced nutritional
________
content.
4) Create antibiotic
__________.
resistance
What is Gene Therapy?
We rely on our genes functioning
correctly, so when a gene is missing or
disease can result.
not functioning, a ________
Gene therapy is a way of
correct gene
putting the _______
back into our cells.
How is it done?
Vector
carries the
new gene to the
cells.
Will this individual produce
offspring with the normal gene?
No, because the
sex cells were not
altered.
Challenges of Gene Therapy:
1)The vector itself could cause the
sick
individual to become _____.
2) The gene has to be delivered to
many & the right kinds of ______.
cells
3)The gene needs to be inserted in
the right part of the cell’s _______.
genome
4) The gene, once present, needs to be
__________.
expressed
