The Code Breaker by Walter Isaacson6/26/2023 ![]() ![]() So that when the virus attacks again, the bacteria remembers it and uses a little guide RNA and a pair of "scissors" (an enzyme that acts as a pair of scissors) and cuts up the invading virus. Whenever viruses attack certain bacteria, those bacteria do something very clever: They take a mugshot and they put it in their own genetic material of the bacteria. On how the gene editing technology CRISPR mimics what the immune system does to bacteria And so this part of the 21st century, I think, will be a biotech revolution, a life sciences revolution. And now with Jennifer Doudna and the things that she and her colleagues have invented, we found ways to rewrite that genome. And in the beginning of this century, in 2000 or so, we sequenced the entire human genome. Now we've come to another particle, a fundamental particle of our existence, which is the gene. This part of the 21st century, I think, will be a biotech revolution, a life sciences revolution in which we'll be able to rewrite the code of life. ![]()
