Genetic Engineering

Genetic engineering is the process of:

• Studying the inheritance of traits.

• Artificially modifying an organism's DNA.

• Observing natural selection in action.

• Cloning identical organisms.

Which of the following is NOT a common technique used in genetic engineering?

• Gene cloning

• Recombinant DNA technology

• Selective breeding

• Gene therapy

A genetically modified organism (GMO) is one that:

• Has been selectively bred for desired traits.

• Has had its DNA altered through genetic engineering.

• Has naturally occurring mutations.

• Is extinct or endangered.

What is a plasmid?

• A type of virus used to deliver genes.

• A circular piece of DNA found in bacteria.

• An enzyme that cuts DNA at specific sites.

• The main chromosome of a eukaryotic cell.

Which enzyme is used to cut DNA at specific sequences?

• Ligase

• Polymerase

• Restriction enzyme

• Transcriptase

What is the purpose of gene therapy?

• To create genetically modified crops.

• To treat genetic diseases by replacing faulty genes.

• To clone endangered animals.

• To improve the nutritional value of food.

Which of the following is an ethical concern regarding genetic engineering?

• The potential for unintended consequences.

• The cost of developing genetically modified organisms.

• The possibility of creating designer babies.

• All of the above

What is a transgenic organism?

• An organism that has genes from a different species.

• An organism that has been cloned.

• An organism that has had its DNA sequenced.

• An organism that is resistant to disease.

How can genetic engineering be used in agriculture?

• To create crops that are resistant to pests and diseases.

• To increase crop yields.

• To improve the nutritional value of food.

• All of the above

What is the human genome project?

• An international effort to map the entire human genome.

• A project to create genetically modified humans.

• A study of the effects of pollution on human health.

• A research program focused on developing new medicines.
