this remarkable mechanism is called crispr-cas9 or crispr for short. crispr-cas9 contains an enzyme that serves as the bacteria's defense mechanism against viruses. when viruses infect the bacteria, the crispr machinery targets the specific section of dna. then the enzyme responds like a pair of scissors and literally cuts the virus's genetic code apart. scientists are now are harnessing this natural mechanism to target and precisely edit dna of numerous organisms. to find out how, i heading to a biotech lab in brooklyn, new york. i'm on my way to genspace, which is the world's first community biology lab. beth tuck is the director of science education at genspace. - we are an open access science lab. we're a community biology lab. - so you're telling me if i'm computer programmer and i want to learn more about biology, i could essentially come down here and take a class and use your facilities? - that's it. - beth is going to show me how to use crispr in the lab to edit a bacteria's genes in a new and novel way. i brought this kit. could you explain a

(eerie dramatic music) - [kondwani] next, we insert crispr construct that will alter their dna. - we're gonna add in the crispr machinery and then change the cells. - [kondwan ah! the crispr machinery targets and edits a specific gene in the e. coli, so that they can adapt to a lethal dose of antibiotics. normally, bacteria can't grow in the presence of this antibiotic. the drug kills the bacteria. - we need to get these bacteria onto this plate, so they can grow. you're just gonna gently drag it across the surface of the plate. - that's it? - yeah, that's it. - [kondwani] over the course of

but in some sensitive situations, crispr technology can be too blunt of a tool. that's because it breaks both strands of the double helix. in rare instances, this can disrupt the gene in unintended ways. but, prime editing is more like a pair of tweezers. it breaks only one strand of the double helix, allowing scientists to very precisely change a single base pair. this is like changing one note in a musical score. - for most diseases with a genetic component, it's believed that in order to treat the disease, you need to precisely change that mutated gene back to the normalna sequence. - [kondwani] this ultra precise technique ans david can replace an individual mutation a on single step of dna, and not an entire section of the ladder. - so you can make those kinds of changes using prime editors. the kinds of changes that we believe could directly correct genetic diase-causing mutations. - in the lab, david has successfully corrected mutations for genetic diseases, including tay-sachs and cystic fibrosis. and he thinks this prime technology will soon be ready to
