- 1. Multiple Choice
Which of the following is not an example of a use of biotechnology?
Growing a kidney in a lab for a transplant
Injecting stem cells into an injury to speed up recovery
Identifying the father of a child by comparing DNA
Identifying the sex of a baby using sonogram
- 2. Multiple Choice
Some scientists hypothesize that genetically modifying salmon using recombinant DNA to increase their size and rate of growth can help meet human demands for protein. Which of these questions addresses the biggest ethical concern scientists should research before releasing the genetically modified salmon into the wild?
Will genetically modified salmon have a less desirable taste than wild salmon?
Will the genetically modified salmon introduce modified genes into the wild salmon population and what will be the impact on the ecosystem?
Will the genetically modified salmon not grow as well in the wild as they do in inland facilities and how much money will be lost if this occurs?
- 3. Multiple Choice
Will a child have the same DNA fingerprints as their parents?
Yes, parents and children have the same genes.
Yes, everyone has the same repeating nucleotide sequences.
No, a child's DNA fingerprint is a combination of both parents' DNA fingerprints.
- 4. Multiple Choice
Which is not a common use of DNA fingerprinting?
to insert foreign genes into organisms
to prove someone's innocence
to identify a crime suspect
- 5. Multiple Choice
How can the length of a DNA fragment be estimated in gel electrophoresis?
Larger fragments travel faster and farther than smaller fragments.
Smaller fragments travel faster and farther than larger fragments.
Larger fragments are more negatively charged so they travel farther.
- 6. Multiple Choice
Most bacteria do not have the ability to break down oil that is accidentally spilled into the ocean by tankers. However, scientists can insert a gene into the DNA of a bacterium to give it the ability to break down the oil. This technology is an example of
Gel electrophoresis
DNA replication
Genetically modified organism
- 7. Multiple Choice
Through what process can scientists artificially change the DNA code of organisms?
gene pool
gene shuffling
genetic engineering
- 8. Multiple Choice
What technique is used when samples of DNA are cut with a restriction enzyme, stained, and then analyzed in a paternity clinic to determine if a family relationship exists between two people?
Cloning
Gel electrophoresis
Gene splicing
- 9. Multiple Choice
Cystic fibrosis results when patients inherit two copies of a recessive CFTR gene. The recessive CFTR genes produce a protein which causes mucus to build up in parts of the body. Having just one dominant CFTR gene allows the body to produce a normal protein. Individuals with one dominant CFTR gene have no cystic fibrosis symptoms. Which question would BEST help researchers identify a potential treatment for cystic fibrosis?
Can a dominant CFTR gene be inserted in patients cells using a virus?
Can recessive CFTR genes recombine with bacterial DNA to be cloned?
Can stem cells be used to change the recessive CFTR genes into dominant CFTR genes in patients cells?
- 10. Multiple Choice
Scientists have inserted a gene that codes for resistance to a biodegradable weedkiller into a certain plant. Which of the following is the most likely benefit of the gene?
plant will be able to produce chemicals to kill weeds around it.
plant is more likely to survive when exposed to the weedkiller.
plant is more likely to die when exposed to the weedkiller.
- 11. Multiple Choice
Which countries are likely to benefit MOST from growing GM crops?
small populations and a lot of resources
small populations and limited resources
large populations and limited resources
- 12. Multiple Choice
Which question MOST likely may have led to the development of gene therapy?
Can undifferentiated cells be used to repair parts of the body?
Can human genes be introduced into the cells of people with genetic disorders using a virus?
Can human genes be integrated into bacterial DNA so bacteria can copy the genes and produce their proteins?
- 13. Multiple Choice
Which question MOST likely may have led to the development of recombinant DNA technology?
Can undifferentiated cells be used to repair parts of the body?
Can human genes be introduced into the cells of people with genetic disorders using a virus?
Can human genes be integrated into bacterial DNA so bacteria can copy the genes and produce their proteins?
- 14. Multiple Choice
A chemical company produced a genetically engineered potato called the New Leaf Superior. This plant produces a chemical that repels insects that might eat the plant. The offspring of the plant will also produce the chemical. What is one possible disadvantage of growing this type of potato?
The chemical will allow too many potatoes to grow, hurting crop yields.
The chemical might be harmful to humans when they eat the potato.
The chemical might kill the plant, causing the soil to lie inactive.
- 15. Multiple Choice
People have produced animals and plants with certain desired characteristics for more than a thousand years. Which technique was first used to produce domestic animals and crop plants with desired characteristics?
genetic engineering
gene mapping
selective breeding
- 16. Multiple Choice
What beneficial impact could genetically engineered crops have on society?
They could create a more stable food supply, as crops could be altered to resist droughts.
They increase genetic variation in crops.
They increase food allergies from crops.
