Questions & Answers

Q: What is CRISPR and how does it work?

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a genetic engineering technique that allows scientists to make precise edits to genes. It uses a guide RNA molecule to target and cut specific DNA sequences, allowing for gene insertion, deletion, or modification.

Q: What are the potential benefits of CRISPR technology?

CRISPR technology offers solutions for deadly genetic diseases like sickle cell anemia and HIV, enabling targeted gene therapy. It also allows for the creation of genetically modified foods with improved traits, such as increased resistance to pests or enhanced nutritional value.

Q: What are the ethical concerns surrounding CRISPR?

One major concern is the concept of designer babies, where embryonic genes are edited to predetermine physical attributes, intelligence, and more. This raises ethical questions about playing God and the potential for creating a societal divide between the genetically enhanced rich and the disadvantaged poor.

Q: How can we address the ethical implications of CRISPR?

It is suggested that a targeted and regulated approach is adopted, particularly regarding embryonic gene editing. Establishing strict ethical boundaries before widespread use would prevent the technology from being exploited for personal gain, ensuring it benefits humanity as a whole.

Summary & Key Takeaways

• CRISPR, a groundbreaking genetic engineering technique, has advanced rapidly since its discovery 70 years ago, enabling precise edits on human genes and cells.

• This technique holds promise in treating deadly diseases like HIV and sickle cell anemia, creating genetically modified foods, and protecting astronauts from space radiation.

• However, the ethical implications of editing human genes, especially in the context of designer babies, and the potential for widening the gap between the rich and poor raise significant concerns.
