BIOTECHNOLOGY EXAM
QUESTIONS AND 100% CORRECT
ANSWERS
What is genetic engineering?
The use of technology to alter the genomes of viruses,
bacteria, and other cells for medical or industrial purposes
What is a transgenic technology?
Inserting a foreign gene into an organism
What is recombinant DNA technology?
To combine the DNA of two organisms to make one of
them more useful for humans
What is recombinant DNA technology used for?
Causing bacteria to reproduce in large vats to get them to
make a large amount of a particular protein, growth
hormone, insulin, etc.
What are the 3 goals of recombinant DNA technology?
Eliminate undesirable phenotypic traits
Combine beneficial traits of two or more organisms
Create organisms that synthesize products humans need
What is another application of recombinant DNA?
The production of safer vaccines
What type of vaccine can result from recombinant
DNA technology?
Hepatitis B vaccine
Bacteria, plants, and animals are genetically
engineered to produce what types of products?
, Biotechnology products
What is one example of transgenic bacteria helping
plants?
Bacteria that have genes spliced in them and are living in
plant roots. This can help plants resist insect toxins.
What is an example of Bacteria that can be genetically
engineered to degrade a particular substance:
Transgenic bacteria have been produced which have the
ability to eat oil after an oil spill.
What are other biotechnology examples of useful
bacteria?
Industry has found that bacteria can be used as filters to
prevent airborne chemicals from being vented into the air.
They can also remove sulfur from coal before it is burned
and help clean up toxic dumps. Furthermore, these
bacteria were given "suicide" genes that cause them to
self-destruct when the job is accomplished.
What are biotechnology examples in mining
Many major mining companies already use bacteria to
obtain various metals. Genetic engineering may enhance
ability of bacteria to extract copper, uranium, and gold
What are examples of genetic engineering in plants?
Plants can also be genetically engineered to make cotton,
corn, soybeans, and potatoes resistant to pests because
their cells now produce an insect toxin. Plants are also
being engineered to produce human hormones, clotting
factors, and antibodies in their seeds. One type of
antibody made by corn can deliver a substance that kills
tumor cells. another made by soybeans can be used as
treatment for genital herpes.
