Improving the Accuracy of Gene Editing Tools

The video discusses advancements in gene editing, focusing on CRISPR CAS9 and a new tool by Dr. Meng Hao called iCast. The iCast tool aims to improve the accuracy and safety of gene editing by controlling access to DNA. The video highlights the potential for treating monogenic diseases like sickle cell anemia but notes the challenges in treating complex diseases like cancer. Future prospects for gene editing advancements are also discussed.

What is the primary function of CRISPR CAS9 in gene editing?

• To prevent DNA mutations

• To enhance protein synthesis

• To replicate DNA sequences

• To cut DNA at specific locations

How does Dr. Meng Hao's tool improve the accuracy of CRISPR?

• By enhancing the replication of DNA

• By using a traffic light system to control access to DNA

• By reducing the size of the CRISPR CAS9

• By increasing the speed of DNA cutting

Why is gene editing more challenging in diseases like cancer?

• Because cancer cells do not have DNA

• Because cancer is caused by a single gene

• Because cancer cells are resistant to CRISPR

• Because cancer involves multiple genetic mutations

Which of the following diseases is mentioned as potentially treatable with CRISPR technology?

• Hypertension

• Sickle cell anemia

• Diabetes

• Alzheimer's disease

What is the expected timeline for the new CRISPR tool to be ready for use?

• It is already available

• Within the next decade

• Within the next five years

• Within the next year
