The Role of Biotechnology Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is biotechnology?

Biotechnology is the alteration and use of living organisms to develop products or technologies. It has been used for thousands of years in selective breeding and more recently in genetic modification and cloning.

How can genetic modification improve crops?

Genetically modified crops can be made resistant to herbicides, pests and drought, which improves productivity and resilience.

What is golden rice and why is it important?

Golden rice is a genetically modified rice containing beta-carotene, which helps prevent vitamin A deficiency and reduces the risk of blindness.

What is mycoprotein and how is it produced?

Mycoprotein is a protein-rich food source derived from the fungus Fusarium. It is grown in fermentation tanks with controlled pH and temperature, and used in vegetarian foods.

How is human insulin produced using biotechnology?

Scientists genetically modify bacteria to produce human insulin by inserting the insulin gene from human cells into bacteria grown in fermentation tanks, then harvesting and purifying the insulin.

What are the benefits of mycoprotein?

Mycoprotein is suitable for vegetarians and is an efficient protein source, as it can be grown in a relatively small space.
