==========
ERIC LANDER: And so the issue became how does DNA replication work. And so I'm about to go into it. Now, I'm going to note we're going to be starting this DNA goes to RNA, goes to protein, and DNA goes to itself. DNA is replicated. It makes RNA. The RNA is used to make protein. This will be what we'll be talking about today and tomorrow. So the first step of that is, how does DNA give rise to more DNA? Well, how do you find an enzyme? How do you do biochemistry? What do you do? AUDIENCE: Assays. ERIC LANDER: Assay. So you've got to grind up the cell. I got to choose a cell in which I'm likely to find an enzyme, grind it up, break it up into different fractions, and test each fraction. That's all biochemists do, right? So what cell might have the enzy...
