...n most proteins are invisible. An ion channel can pass more than 1 million ions per second,' Sachs said. That's a big enough output to measure in real time. The programs allow you to not only "watch" an ion channel molecule at work, they provide specific quantitative results on how it works, on how fast ......, the rest of the colony may starve -- and fail to pass on their nearly identical genes.
