Test your knowledge with these top questions!
Medical researchers cure genetic diseases with CRISPR by doing what?
By precisely correcting disease-causing mutations, CRISPR can permanently cure conditions. In 2023, the FDA approved the first such therapy for sickle cell disease.
Bacteria naturally use the CRISPR system to perform what function?
Bacteria use CRISPR as an adaptive immune system, storing snippets of invading viral DNA to quickly recognize and destroy the virus if it attacks again.
Scientists use the Cas9 protein, a key CRISPR component, to do what to DNA?
Cas9 acts as a pair of molecular scissors that snips the DNA strand. This precise cut allows scientists to rely on the cell's natural repair machinery to alter the gene.
Gene-editing tool CRISPR uses a custom RNA molecule to do what?
This custom guide RNA perfectly matches the target sequence, acting like a GPS to ensure the Cas9 enzyme cuts only the intended gene without damaging others.
Gene-editing system CRISPR uses the Cas9 protein to act as what biological tool?
The Cas9 protein acts as molecular scissors by creating double-stranded breaks in DNA at specific locations.
Bacteria originally evolved the CRISPR mechanism to defend themselves against what threat?
CRISPR sequences allow bacteria to recognize and destroy the genetic material of invading viruses during a secondary infection.
CRISPR technology uses a custom-designed piece of RNA to perform what crucial step?
The guide RNA is engineered to match a specific DNA sequence, ensuring the Cas9 enzyme reaches the correct genetic target.
Scientists named CRISPR for its "palindromic" repeats, meaning the DNA sequences do what?
Palindromic repeats in the CRISPR array consist of base pair sequences that are identical when read in the 5' to 3' direction on both strands.
