Exploring Genetic Engineering Concepts

When did direct modification of genes begin?

• 1990s

• Mid-20th century

• 1970s

• 1800s

What is an example of early human influence on animal genetics?

• Breeding wolves to create different dog breeds

• Cloning

• Gene editing in mice

• Creating glow-in-the-dark fish

What is an example of a trait that early humans may have selected for in dogs?

• Glowing fur

• Resistance to diseases

• Ability to fly

• Docility and obedience

How were sweeter and larger apples developed?

• Natural evolution

• Use of fertilizers

• Selective breeding over generations

• Genetic modification in the lab

Why is genetic engineering considered more precise than traditional breeding methods?

• It can be done in nature without human intervention

• It is faster

• It allows for specific traits to be selected

• It is cheaper

What is recombinant DNA?

• Combining DNA from different organisms

• DNA taken from fossils

• DNA that replicates rapidly

• Removing DNA from an organism

What is a genetically modified organism (GMO)?

• An organism modified through selective breeding

• An organism with DNA inserted from another species

• An organism that has evolved naturally over time

• An organism found in the wild with unique traits

Why might genetic modification of crops be controversial?

• It is too expensive

• It can make foods less nutritious

• Crops grow too large to harvest

• Concerns over long-term effects and nutrition

What potential benefit does recombinant DNA technology offer?

• Creating larger animals

• Producing insulin through bacteria

• Making plants glow in the dark

• Increasing the intelligence of species

What is a key ethical question in genetic engineering?

• Can we use genetic engineering to change weather?

• Is it ethical to modify the human genome?

• Should all foods be genetically modified?

• Should we create new species?
