Biotechnology - Review 2025

1. What is genetic engineering?

• Using genetics to improve engineering practices
• Manipulating the genetic information of an organism

• Improving our understanding of genetics using engineering
• Splicing together the bodies of two different species

2. What is gel electrophoresis?

• A process that uses recombinant DNA to insert genes from one organism into the DNA of another organism
• The process of creating an exact replica of an organism
• The process of using electricity to separate DNA fragments to create a DNA profile
• A project that studied and sequence the entire human genome.

3. Which of these is an example of genetic engineering?

• A new breed of dog created by selecting parents with desirable characteristics
• Resurrection of the woolly mammoth using fossilized DNA
• Using DNA sequencing to identify the people present at a crime scene
• A tomato plant that has genes from a snapdragon plant that allow it to produce antioxidants

5. The diagram shows the DNA fingerprints of a baby and four couples. A hospital wants to identify the parents of the baby. Based on the DNA fingerprints, which couple is most likely the parents of the baby?

• Couple W
• Couple X
• Couple Y
• Couple Z

6. What is used to cut DNA into smaller fragments? (a)  

• Restriction Enzymes
• Carbohydrates
• Plasmids
• Recombinant DNA

7. What is being used to carry the new gene into the bacterial cell in recombinant DNA?

• A plasmid
• A virus
• A chromosome
• A needle

Cloning a small amount of DNA to create larger amounts of the DNA/genes is called ..

• PCR (Polymerase Chain Reaction)

• Recombinant DNA

• DNA fingerprinting

• Restriction Enzymes

9. A lot of the debate around genetically modified organisms is concerned with whether or not it is morally right or wrong to modify the DNA of organisms. What is the name of this issue?

• An ethical issue
• A philosophical issue
• A hypothetical issue
• A political issue

What is a potential benefit of using genetically modified organisms (GMOs) for agriculture?

• Increased crop yields and resistance to pests

• Decreased need for technology in farming

• Reduced variety of crop species

• Enhanced natural beauty of the landscape

DOK Level 3: Strategic Thinking

This laboratory procedure is known as DNA Fingerprinting. Why is this beneficial for forensics?

• Helps to analyze proteins rather than DNA

• Creates a fingerprint

  which can identify the suspects DNA

• It is not reliable or helpful when solving crimes

• DNA does not need to be collected and used because everyone has the same pattern
