Biotechnology may make it possible to
customize the genetic makeup of crop
plants so they can grow in exceptionally
dry or wet, hot or cold climates.
Agriculture
Scientists have inserted the genes that
code for therapeutic proteins into a
variety of commonly grown crops such
as tobacco, corn and soybeans.
Medicine
Approved in 1996, Roundup® Ready
cotton is resistant to applications of
Roundup® herbicide designed to kill
weeds. Farmers have to spend less time
plowing fields and their crop production
increases.
Agriculture
Bovine Somatotropin (BST) BST is a
naturally occurring protein hormone in
cows that causes them to produce milk.
BST improves milk production by as
much as 20 percent and is now used by
farmers in over 30% of the nation's
cows.
Agriculture
Many animal feed products are
enhanced with proteins to boost
nutrition and control disease.
Agriculture
Corn with the Bt gene is an insectprotected variety that provides a high
level of genetically introduced
protection against European corn borer
and corn earworm, protecting crops
from ear damage and yield loss.
Agriculture
Lactaid® milk products produced using
the enzyme lactase.
Food and Consumer Goods
Fruit juices are made using the
enzyme pectinase which breaks down
the pulp into juice.
Food and Consumer Goods
Fabric detergents are becoming more
effective because of the addition of
enzymes to their active ingredients.
Contact lens solutions contain enzymes
to break down proteins that build up
on lenses.
Food and Consumer Goods
Food and Consumer Goods
Using microbial fermentation to
produce an abundant amount of pepsin
or rennet (naturally found in a cow’s
stomach) for cheese production.
Microbes are grown so that their
amino acids can be used to produce a
product such as Equal sweetener.
Food and Consumer Goods
Food and Consumer Goods
Using methane-producing bacteria (or
methane gas from waste lagoons) to
heat homes in third-world countries.
Environment
Microbes can clean up waste water
before it enters streams and lakes.
Environment
Sewage plants collect methane gas to
fuel generators or air compressors.
Microbes are capable of cleaning up
fuel spills from gas stations
Environment
Environment
There is a fungus which is used to
break down a wood preservative that
contaminates the soil near old
sawmills.
Environment
Following the major oil spill in
Alaska's Prince William Sound,
natural oil-eating bacteria to help
clean up the mess were used. Followup studies suggest that the microbes
did as good a job in cleaning up soiled
beaches as high-pressure hoses and
detergents could have done.
Environment
Flu vaccine that is not a shot- it is a
nasal spray.
Medicine
New tests (assays) to diagnose
inherited diseases and common
illnesses like strep throat have been
developed through Biotechnology.
Medicine
Monoclonal antibodies that fight
cancer cells.
Medicine
Human Genome Project- to locate and
identify every gene in the human body
and what it does.
Medicine
Test strips that indicate the level of
glucose in the blood (biosensors).
Human growth hormone to counteract
dwarfism.
Medicine
Medicine
DNA found in blood evidence locates a
suspect at the crime scene.
Fingerprints on a murder weapon prove
a suspect handled it.
Forensics
Forensics
Scratch marks on a bullet that killed
a victim are compared to a bullet
fired from a weapon to see if the
weapon is the murder weapon.
Forensics
Plaster casts of shoe prints place a
suspect at the crime scene.
Forensics
Temperature of a corpse’s liver is
measured to estimate the time of
death.
Forensics
Areas of Biotechnology Activity
Roll the dice to form 3-4 teams of 2-3 students.
Have each team choose a school appropriate name.
Make a score table on the board.
Call on teams in order.
Read the clue
Team 1 gets to stand under the sign for the answer
Team 2 may challenge.
The team that gets the right answer gets 1 point.
If the challenging team is wrong they get negative 1/2 point.
The next question if for team 2, and team 3 may challenge.++
