Unit Summary
This unit covers the human genome's importance and genetic engineering, outlining steps, benefits, and risks. It explores gene technology in agriculture and medicine, focusing on ethical considerations, and societal impacts, and evaluating scientific limitations and risks.
Lesson Summary
You will learn to describe what genetic engineering is, some potential benefits, risks and ethical issues and the main steps in the process.
Key Notes
- Genetic engineering involves modifying the genome of an organism by adding DNA from another organism.
- The aim of genetic engineering is to introduce a desirable characteristic.
- Examples of genetically engineering crop plants and bacteria to benefit humans.
- Benefits must be weighed against risks and ethical issues.
- The main steps in the process of genetic engineering.
Vocabulary To Learn
- gene: a section of DNA carrying the genetic code that provides the instructions for a feature or process
- genetic engineering: the process of introducing a gene from one organism into the genome of another organism
- risk: the chance that an outcome (usually a negative one) will occur
- ethical question: a question about whether something is right or wrong
- vector: a plasmid or virus used to introduce a gene from one organism into the genome of another organism
Common Mistakes To Avoid
- Over-estimating the risks of genetic engineering and genetically modified (GM) organisms.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Genetic engineering involves modifying the genome of an organism by adding DNA from another organism. The aim of genetic engineering is to introduce a desirable characteristic.
2. Define this scientific word and use it in context. 'gene'
a section of DNA carrying the genetic code that provides the instructions for a feature or process. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Over-estimating the risks of genetic engineering and genetically modified (GM) organisms. Correction: The lesson explores the need to weigh up possible benefits, risks and ethical questions when making decisions about genetic engineering.
