TRANSCRIPT
Differentiate between adaptive and assistive bioengineered products.
Key concepts/skills:Level 1: Define key vocabulary. Level 2: Differentiate between adaptive and
assistive technology.Level 3: Identify examples of biofuels,
bioengineered medicines, and bioengineered pest management, and explain why each is either assistive or adaptive technology.
Differentiate between adaptive and assistive bioengineered products.
Key vocabulary:Bioengineering
Biofuels Bioengineered food
Assistive bioengineering Genetic engineering Gene splicing Bioengineered medicine
Adaptive bioengineering Pest management
Differentiate between adaptive and assistive bioengineered products.
I. BioengineeringA.The application of
engineering to living things such as humans and plants
Differentiate between adaptive and assistive bioengineered products.
1. Assistive Bioengineering a. engineering that results in a product or process that helps living organisms but does not change them permanently b. hearing aid, glasses, prosthetic limbs, band aids
Differentiate between adaptive and assistive bioengineered products.
2. Adaptive Bioengineering
a. engineering that results in a product
or process that changes
living things
b. artificial heart, artificial organs,
cochlear implants
Differentiate between adaptive and assistive bioengineered products.
I. Bioengineered ProductsA. Medicine – good genes or proteins are
manufacture to replace bad ones using bacteria
1. Examples- insulin, interferon2. Genetic engineering – any change to
an organism’s DNA
3. Gene splicing – replacing bad or undesired genes with working or desired genes
Differentiate between adaptive and assistive bioengineered products.
B. In Agriculture – making crops resistant to
disease herbicide and frost
1. Herbicide resistant crops (corn)
2. Plants like tomatoes that will ripen on
vine and stay fresh longer
Differentiate between adaptive and assistive bioengineered products.
C. Biofuels – Ethanol is a clean burning fuel for
engines made from plants.
1. Cellulose > sugars > ethanol
2. Bacterium control this process
3. Problem is which plants
should be used to make ethanol?
4. Plants used are corn, sugar, sugar
beets, switchgrass, algae
