Introduction to Genetic Engineering
Date
Unit # and Name:

Unit 3 : Genetic Engineering
Page #
Objective
• I will be able to describe how genetic
engineering is used to produce biomedical
and agricultural products.
What is biotechnology?
• Biotechnology: the manipulation of
organisms or their components to make
useful products
• Scientists can modify
specific genes and move
them between organisms
as distinct as bacteria,
plants, and animals!
• Check this out…
Glowing Mice!
Glowing pigs!
Want a glowing pet fish?
How about glowing
tobacco?
Should we make glow
in the dark people?!
Mighty mouse gene!
How might this be
useful?
Mighty cows = more
meat!
How about giant
vegetables?
Basket ball size
tomato?
Watermelon anyone?
Featherless Chickens…
Flavr Savr Tomato
• The FLAVR SAVR
tomato was the first
genetically
engineered crop
product to be
commercialized.
• Tomatoes didn’t
spoil because the
gene for the “fruit
softening” protein
was altered.
Glowing Cat and Stem Cell Eyes

What is Genetic
Engineering?
• Genetic
Engineering:
Manipulating
organisms genes for
practical purposes
– Changes the
organisms DNA and
gives it new traits
– Also known as:
genetic manipulation
What is genetic
engineering used for?
Two main purposes:
1. Creating new
biomedical products
2. Creating new
agricultural products
Biomedical Products
• Using living things and
biological processes in
connection with medicine
• Examples:
– Creating insulin to help
people with diabetes
– Human growth hormone:
treats stunted growth
– Anti-clotting factors to help
heart attack patients
Mouse growing human
ear cartilage!
1997. The mouse had been implanted with a tumor of human cartilage and a form had
been placed over the back so that the tumor would grow into the shape of an ear.
While the mouse wasn’t genetically engineered to make a human ear, the production
of the cartilage tumor cells involved genetic engineering.
Agricultural Products
• Using biotechnology in connection with
growing and producing food (plants and
animals)
• Examples:
– Pest-resistant crops
– Non-spoiling fruits and vegetables
– Peanuts that don’t trigger allergies
– “Meatier chickens” combined with egg-laying
chickens
Spider silk producing
goats?!
• This baby goat will produce milk that contains spider silk
proteins… a tough, flexible material that could be could
be used for a vast array of products,
– from artificial ligaments to super-strong replacement tendons or
even body armor
How do they make these
products?
• Review: Gene = a section of DNA that
codes for a physical trait
• If a gene produces a trait, we can use
technology to isolate the gene and insert it
into another organism
– Example: Gene
for weight was
inserted into mice
in order to study
obesity!
CFU #1
Genetic engineering has produced chickens
whose eggs contains proteins that can be used
as medicines. This effect was produced by:
A mixing foreign genes into the eggs
B injecting foreign genes into the chicken’s
reproductive organs
C inserting foreign genes into fertilized
chicken eggs
D genetically changing the nutritional needs
of the chicken’s offspring
What is the result?
• Recombinant DNA: DNA in which
genes from two different sources, often
different species, are combined in one
organism
What are some
other uses for
biotechnology?
•
•
•
•
•
•
Diagnosis of Diseases
Gene Therapy
Pharmaceutical Products
Forensics: DNA Fingerprinting
Cloning
And more!!!!
CFU #2
The bacterium Agrobacterium tumefaciens
infects plants, and a portion of its DNA is
inserted into the plant’s chromosomes. This
causes the plant to produce gall cells, which
manufacture amino acids that the bacterium
uses as food. This process is a natural example
of:
A polyploidy
B genetic manipulation
C grafting
D hybridization
Salmon Video
Mini Quiz
Do Now
1. Genetic engineering typically involves:
A Carefully studying the lungs of the
organism
B Changing the genes of an organism
by inserting foreign DNA into the
organism
C Mating the organism to another
species to produce a new species
D Creating mutations in the organism
2. Genetic engineering has produced
goats whose milk contains proteins that
can be used as medicines. This effect
was produced by:
A mixing foreign genes into the
milk
B injecting foreign genes into the
goats’ udders
C inserting foreign genes into
fertilized goat eggs
D genetically modifying the
nutritional needs of the goats’
offspring
3. Give a shout out to one classmate for
doing something great this week!
