Genetic Engineering Quiz

What is the primary goal of gene editing techniques?

• To create new genes

• To modify or correct existing genes

• To remove all genes from an organism

• To study gene expression without altering the genome

Which of the following is a common use of GMOs in agriculture?

• Decreasing crop yield

• Increasing susceptibility to pests

• Enhancing nutritional content of crops

• Reducing the shelf life of produce

What is a key difference between reproductive cloning and therapeutic cloning?

• Reproductive cloning aims to create a new organism, while therapeutic cloning aims to produce tissues or organs for transplantation.

• Therapeutic cloning creates a new organism, while reproductive cloning does not.

• Reproductive cloning uses adult DNA, while therapeutic cloning uses embryonic DNA.

• Therapeutic cloning can create whole organisms, while reproductive cloning cannot.

In biopharmaceutical production, what role do genetically modified organisms play?

• They are used to test the efficacy of new drugs on humans directly.

• They serve as biofactories to produce therapeutic proteins.

• They are used to enhance the side effects of drugs.

• They are solely used for the production of antibiotics.

What does CRISPR technology primarily utilize to edit genes?

• Viral vectors

• RNA interference

• Guide RNA and Cas9 enzyme

• Restriction enzymes

Which of the following is a major ethical consideration in genetic engineering?

• Increasing the speed of computers

• The potential to create new diseases

• The impact on global warming

• The use of fossil fuels

What is the purpose of gel electrophoresis in genetic engineering?

• To create new DNA sequences

• To cut DNA into smaller pieces

• To separate DNA fragments based on size

• To combine DNA from different organisms

What is the main purpose of PCR (Polymerase Chain Reaction) in genetic engineering?

• To decrease the amount of DNA

• To make millions of copies of a specific DNA segment

• To change the sequence of DNA

• To visualize DNA fragments

What is the goal of selective breeding in agriculture?

• To decrease genetic diversity in crops

• To increase crop susceptibility to diseases

• To enhance desirable traits in crops or livestock

• To reduce the growth rate of crops or livestock

What is bacterial transformation commonly used for in genetic engineering?

• To remove bacteria from an environment

• To introduce a foreign piece of DNA into a bacterial cell

• To kill bacterial cells

• To study the effects of antibiotics on bacteria
