Review Questions
1. What does DNA fingerprinting involve?
DNA fingerprinting involves analyzing and comparing DNA samples from different individuals. The technique uses PCR (polymerase chain reaction) to amplify specific DNA regions and then separates them using gel electrophoresis. The resulting pattern of bands is unique to each individual, making it a valuable tool for forensic investigations, paternity testing, and identifying genetic diseases.
2. What is a genetically modified organism (GMO)?
A genetically modified organism (GMO) is an organism that has been altered at the genetic level by intentionally manipulating its genes. This is done through the use of recombinant DNA technology, where genes are inserted, removed or modified in the organism’s DNA. GMOs can be created for a variety of reasons, such as improving crop yields, making crops resistant to pests or diseases, or producing medicines.
3. What are some of the potential benefits and drawbacks associated with genetically modifying crops?
Potential benefits of genetically modified crops include increased crop yields, decreased use of pesticides and herbicides, and improved nutritional content. Genetically modified crops may also be more drought and heat tolerant, making them better able to withstand challenging environmental conditions.
Drawbacks of genetically modified crops include potential health and environmental risks, such as the creation of superweeds or the loss of biodiversity. Additionally, some people have ethical concerns about the genetic modification of organisms and believe that it goes against the natural order.
4. What is gene therapy?
Gene therapy is a medical technique used to treat and potentially cure genetic diseases. It involves delivering a functional copy of a faulty gene to affected cells, either through direct injection or insertion into a vector (a carrier that is then inserted into the patient’s body). Gene therapy has the potential to cure diseases that were previously considered incurable, but it is still in early stages of development and carries risks.
Conclusion
Staying informed and up-to-date on scientific advancements is important for website operators who aim to provide accurate information to visitors. In this article, we reviewed Section 13.3 of the Genetic Engineering chapter and provided answers to the provided review questions. It is important to continue learning about genetic engineering and its potential applications and impacts.
