New ways of manipulating genetic code–of writing, reading, copying, and editing the laguage of life–are cropping up almost on a daily basis. Our daily lives can change forever thanks to these advancements in biotechnology. It still remains to be seen if these changes are good or bad. I approach them with some reserve, with cautious optimism:
Bacteria, like human beings and almost every other living thing, keeps its genetic code in a library of DNA molecules. But to use that code, the organism copies the DNA into a related molecule called RNA. Cas9 can be paired with an RNA transcript to target a matching DNA sequence and cut it. That kills viruses, but scientists use it to cut DNA in exactly the place they want. The result is not so much like using a word processor as a biology lab version of what movie editors had to do back when they spliced together pieces of film.
