What is recombinant DNA?

• Adding DNA from one organism into the DNA of another
• DNA which has been changed over generations by natural selection
• DNA that causes genetic disorders
• DNA that has been sequenced

Another name for GMO (Genetically Modified Organsim) is ____________.

• Transgenic
• Transplanted
• Transducted
• Plasmid

Which suspect left the blood stain?

• Bob

• Sue

• John

• Lisa

In the United States, there has been relatively little experimentation involving the insertion of genes from other species into human DNA. What is one reason for the limitations of these experiments?

• The subunits of human DNA are different from the DNA subunits of other species.

• Inserting foreign DNA into human DNA would require using completely new techniques.

• Human DNA always promotes human survival, so there is no need to insert foreign genes into it.

• There are many ethical questions to be answered before inserting foreign genes into human DNA.

A farmer is considering the advantages of cloning a herd of cattle from a single cow. What is one advantage of a cloned herd?

• All cattle in the herd would have the most desired traits.

• All cattle in the herd would have more genetic variation.

• All cattle in the herd would have more resistance to diseases.

• All cattle in the herd would have much longer life spans.

Scientists have produced a genetically modified orange tree that is resistant to disease. Which of the following is the best example of a potential benefit to society that could result from this biotechnology?

• reduction in orange crops produced

• increase in orange crops produced

• increase in the cost of orange crop

• a change in the distribution of insects that pollinate orange flowers

Scientists have inserted a gene that codes for resistance to a biodegradable weedkiller into a certain plant. Which of the following is most likely to occur when this gene is inserted?

• The plant will become able to produce chemicals to kill weeds around it.

• The plant will become able to produce chemicals to kill weeds around it.

• The plant will become able to convert the weedkiller into fertilizer.

• The plant is more likely to survive when exposed to the weedkiller.

GMO crops are regularly met with opposition, Golden Rice is grown and distributed in regions where rice consumption is high and variety in diet is low. Which of the following explains a benefit of using Golden rice in these areas?

• Golden Rice is bio-engineered and is yellow as a result.

• Golden Rice allows regions with a low variety of food to receive necessary nutrients.

• Beta-carotene is a lab-created nutrient that has unknown effects.

• Producing Golden Rice will result less variety of food grown.
