Questions & Answers

Q: How does CRISPR edit DNA?

CRISPR uses a protein called Cas9 and a guide RNA to target and cleave specific DNA sequences, leading to genetic modifications.

Q: Are there any risks or side effects of using CRISPR?

One major concern is off-target effects, where unintended changes occur in the genome. There is also ethical debate surrounding germline editing and potential long-term consequences.

Q: What are some current and upcoming applications of CRISPR in agriculture?

CRISPR can be used to develop disease-resistant crops, increase yield, improve nutritional content, and enhance food preservation.

Q: How are the delivery systems for CRISPR developed?

Researchers use lipid nanoparticles or viral vectors to deliver CRISPR components into target cells. The choice of delivery system depends on the specific application.

Summary & Key Takeaways

• CRISPR was discovered as a bacterial antiviral defense system and has since been adapted as a tool for editing DNA.

• Current uses of CRISPR include gene therapies for diseases like sickle cell anemia, thalassemia, and muscular dystrophy.
