TED: What you need to know about CRISPR | Ellen Jorgensen

The video discusses CRISPR, a genome-editing technology that is both versatile and controversial. It explains the CRISPR mechanism, involving Cas9 protein and guide RNA, and its applications in scientific research. Despite being labeled as 'cheap' and 'easy,' CRISPR presents challenges, including regulatory issues and patent battles. The video emphasizes the importance of understanding CRISPR's implications and the societal responsibility in guiding its development.

What is one of the main reasons CRISPR technology is considered controversial?

• It is too expensive for most researchers.

• It can be used to edit human embryos.

• It is a new technology with no historical basis.

• It has no practical applications.

What are the two main components of the CRISPR system?

• DNA polymerase and ribosome

• Cas9 protein and guide RNA

• RNA polymerase and DNA ligase

• Helicase and topoisomerase

How does the guide RNA function in the CRISPR system?

• It degrades the target DNA sequence.

• It directs the Cas9 protein to the target DNA sequence.

• It acts as a template for DNA synthesis.

• It repairs the DNA after cutting.

What is a significant advantage of CRISPR in terms of cost?

• It reduces the cost of materials from thousands to hundreds of dollars.

• It requires no specialized equipment.

• It eliminates the need for a lab.

• It is free to use for all researchers.

Why is it challenging to perform CRISPR experiments outside of professional labs?

• It is illegal to perform CRISPR outside labs.

• The materials are not available to the public.

• The process requires precise conditions and expertise.

• The equipment is too large for home use.

What is a potential risk associated with using CRISPR in whole organisms?

• It is ineffective in all organisms.

• It can cause immediate cell death.

• It may lead to unintended genetic mutations.

• It requires constant monitoring.

What responsibility do we have as a society regarding CRISPR technology?

• To ban its use entirely.

• To ensure it is only used for commercial purposes.

• To leave its development solely to scientists.

• To guide its development and ensure positive outcomes.
