We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.
Sentiment: POSITIVE
Before the Human Genome Project, most scientists assumed, based on our complex brains and behaviors, that humans must have around 100,000 genes; some estimates went as high as 150,000.
