Gene Therapy and CRISPR Concepts

The video explores the revolutionary gene editing technology CRISPR, highlighting its potential to cure hereditary diseases like sickle cell anemia. It contrasts CRISPR with traditional gene therapy, which faced setbacks due to safety concerns. The video discusses ethical issues surrounding CRISPR, such as the possibility of designer babies. It also covers the history and revival of gene therapy, emphasizing recent advancements and ongoing challenges.

What is CRISPR primarily used for in the context of genetic editing?

• To change single letters in DNA

• To delete entire chromosomes

• To create new genes

• To duplicate existing genes

What genetic condition does Pierceton Charles suffer from?

• Sickle cell anemia

• Cystic fibrosis

• Muscular dystrophy

• Hemophilia

What is a major ethical concern associated with CRISPR technology?

• It can only be used on plants

• It may lead to the creation of designer babies

• It cannot be used on humans

• It is too expensive to use

What was Ashanthi De Silva's genetic disorder?

• Cystic fibrosis

• Sickle cell anemia

• Hemophilia

• ADA deficiency

What was the main issue that led to Jesse Gelsinger's death during a gene therapy trial?

• The delivery vehicle caused an immune response

• The wrong gene was inserted

• The gene itself was toxic

• The therapy was not approved by the FDA

What was a significant factor in the decline of support for gene therapy in the early 2000s?

• Success of alternative treatments

• The death of Jesse Gelsinger

• FDA approval issues

• Lack of funding

What is the primary goal of gene therapy?

• To create new genetic disorders

• To replace defective genes with healthy ones

• To eliminate all genetic variations

• To enhance physical abilities

What is a potential benefit of CRISPR over traditional gene therapy?

• It is more expensive

• It requires more time to work

• It is less precise

• It can repair genes directly

What is the main challenge in achieving a permanent cure with gene therapy?

• Difficulty in finding patients

• High cost of treatment

• Uncertainty about long-term benefits

• Lack of available genes

What is a key reason for the renewed interest in gene therapy?

• Government mandates

• Increased public awareness

• Development of safer vectors

• Discovery of new diseases
