Genetic Engineering Quiz

What is the primary goal of genetic engineering?

• To create new species

• To transfer desirable traits between organisms

• To eliminate all genetic disorders

• To increase the lifespan of organisms

Which of the following is an example of genetic engineering in agriculture?

• Golden rice containing beta-carotene

• Sheep producing drugs in their milk

• Crops resistant to diseases and herbicides

• Bacteria producing insulin

What is a major challenge in gene therapy for inherited disorders?

• Creating a new gene from scratch

• Ensuring the gene is not rejected by the body

• Transferring the gene to every cell in the body

• Finding the right gene to transfer

How can gene therapy potentially solve inherited disorders?

• By giving a person the healthy version of the gene

• By altering the person's diet

• By creating a new organism

• By removing the faulty gene

What is a potential solution to the challenge of transferring a gene to every cell in the body?

• Increasing the dosage of the gene

• Applying the gene therapy multiple times

• Transferring the gene at the egg or embryo stage

• Using stronger vectors

What is one potential benefit of genetically modified crops?

• They can grow without sunlight

• They are immune to all diseases

• They can produce more food for less cost

• They can survive in any environment

What is a concern regarding the impact of GM crops on the environment?

• They might cause new diseases

• They could outcompete local plants

• They will not grow in farmer's fields

• They will require more water

What is the first step in transferring a gene from one organism to another?

• Introducing the vector to the organism

• Cutting the organism's DNA

• Inserting the gene into a vector

• Finding and isolating the desired gene

Which of the following can be used as a vector in gene transfer?

• A plant leaf

• A human cell

• An animal embryo

• A virus or bacterial plasmid

What is the purpose of using enzymes in the gene transfer process?

• To make the organism resistant to diseases

• To cut and isolate the desired gene

• To speed up the growth of the organism

• To enhance the organism's natural abilities
