Biotechnology ch. 12

Which is a concern of scientists when genetically modifying plants?

• Plants will pass on diseases to animals.

• There will be a decrease in biodiversity.

• Plants will have a longer growing season.

• There will be a decrease in revenue for pesticide manufacturers.

How does biotechnology most likely affect Oklahoma’s population?

• Jobs are created and attract more people to the area.

• Research advancement causes people in need of medicines to move to the area.

• People are not concerned with biotechnology so the overall population is not impacted.

• The issue causes controversy and people hesitate to live in a state where a large amount of research takes place.

Which best describes a controversial issue associated with the use of genetically modified crops?

• the use of genetically modified crops to increase potential yield

• the short term use of genetically modified crops in famine stricken countries

• the development of genetically modified crops which are resistant to herbicides

• the long term effects which may arise from the use of genetically modified crops

Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans?

• The bacteria have been grown on a petri dish containing insulin.

• The bacteria have been genetically engineered to contain the DNA needed to produce insulin.

• The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.

• The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.

Which area of biotechnology would most likely create ethical issues within human society?

• insulin production by bacteria

• organ cloning for use in transplants

• genetic engineering to improve agricultural yields

• DNA and forensic testing of crime scene evidence

An application of using DNA technology to help environmental scientists would be ___.

• use PCR to analyze DNA at a crime scene
• create a tobacco plant that glows in the dark
• clone the gene for human growth hormone to treat pituitary dwarfism
• make transgenic bacteria that can be used to clean up oil spills more quickly than do the natural bacteria

Which of the following would be an example of gene therapy technology?

• development of a nasal spray that contains copies of the normal gene that is defective in person with cystic fibrosis
• cutting DNA into fragments with restriction enzymes
• modifying E. coli to produce indigo dye for coloring denim blue jeans
