Genetic Engineering Quiz

What is the basic idea of genetic engineering?

• Creating new organisms with artificial characteristics

• Using chemicals to alter the DNA of organisms

• Finding organisms with desirable characteristics and transferring their genes to other organisms

• Manipulating the environment to change the traits of organisms

What is the potential solution to transferring a healthy gene into every cell in the body for gene therapy?

• Using advanced surgical techniques

• Administering the gene through a series of vaccinations

• Transferring the gene at an early stage of development

• Injecting the gene directly into the bloodstream

What is one of the main issues with genetically modified crops?

• Uncertainty about their potential effects on human health

• Lack of resistance to diseases

• High cost of production

• Inability to produce desirable characteristics

What is the vector used to transfer the gene into the desired organism?

• Fungus

• Algae

• Bacterial plasmid

• Virus

What is the purpose of genetically engineering sheep to produce substances like drugs in their milk?

• To make the sheep resistant to diseases

• To increase the milk production of the sheep

• To extract and use the substances to treat diseases

• To improve the taste of the milk

What is the potential benefit of genetically modified crops?

• Producing more food for less money

• Reducing the need for water and sunlight

• Increasing the shelf life of the crops

• Enhancing the natural flavor of the crops

What is the concern regarding genetically modified plants making their way into the wild?

• They might become less nutritious

• They might lose their desirable characteristics

• They might become more susceptible to diseases

• They might out-compete local plants and change the whole ecosystem

What is the purpose of gene therapy?

• To give a person a healthy version of the gene to fix inherited disorders

• To create new genes from scratch
