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
3
What is a Genetically Modified Organism (GMO)?
Is any organism that has acquired one or more
______ by artificial means.
genes
A GMO is said to be
transgenic
This means that the GMO containsDNA from
different species.
4
What are the benefits to genetically modified
plants and animals?

• To make pesticide __________ plants.
• GM plants can produce natural
• __________.
• To increase ________ content.
• To make food last _______.
• Getting food to the market _______.

resistant
pesticide
vitamin
longer
faster
5
Some Examples of GM Plants
Golden Rice is genetically _________ so it
contains ______ from daffodils to _________
the production of ______________ (an important
precursor of Vitamin A).
modified
genes
increase
beta-carotene
6
Scientists have also genetically _________ sweet
corn so it contains _____ from a bacteria that
allow the corn to produce a natural __________.
modified
genes
pesticide
7
How do scientists genetically modify plants?
8
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.
9
What are the risks of GMOs?

• Increase in food
• ________.
• The creation of new
• __________.
• 3) Reduced ________ content.
• 4) Create antibiotic __________.

toxicity
allergens
nutritional
resistance
10
What is Gene Therapy?
We rely on our genes functioning correctly, so
when a gene is missing or not functioning, a
________ can result.
disease
Gene therapy is a way of putting the _______
gene back into our cells.
correct
11
How is it done?
Vector carries the new gene to the cells.
12
Will this individual produce offspring with the
normal gene?
No, because the sex cells were not altered.
13
Challenges of Gene Therapy

• The vector itself could cause the individual to
  become _____.
• 2) The gene has to be delivered to
• many the right kinds of ______.
• The gene needs to be inserted in
• the right part of the cells _______.
• 4) The gene, once present, needs to be
  __________.

sick
cells
genome
expressed
