Benefits of Gene Technology 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.

How can genetic testing benefit someone with a family history of a genetic disease?

It can show if they carry a faulty allele, so they can get early advice and treatment.

Parents can choose an embryo without the faulty allele, so the baby is less likely to be born with the disease.

By studying a patient's genes, doctors can pick drugs that are more likely to work and cause fewer side effects.

GM bacteria can make large amounts of pure human proteins, which makes these medicines cheaper and safer for many patients.

Some GM crops grow faster or give higher yields, so more food can be produced on the same area of land.

They need fewer insecticide sprays, so there is less chemical use and less harm to other organisms.

Crops can be modified to survive with little water or in salty soils, so farmers can still grow useful crops.

They can reduce vitamin deficiency and related diseases in people who depend on that crop for food.

It shows how the microbe is spreading and changing, which helps scientists track outbreaks and design better treatments or vaccines.

To add working copies of genes to their cells, so symptoms are reduced or the disorder may be cured.
