Most of us are aware that DNA and RNA are the molecular machinery that synthesise proteins and allow the complex reactions of life to take place, but actually visualising the processes is a considerable mental leap.
Most such visualisations rely on visual simplifications that actually present a false impression of the processes involved, but via Eric Drexler we discover the following examples by Drew Berry, which are apparently much truer to the actual processes that occur. Take the seven or so minutes needed to watch this, and you’ll be set up for your daily dose of scientific sensawunda for the rest of the week – biochemistry is incredibly awesome:
Aside from the sheer wow-factor of seeing molecules acting like high-precision machines deep at the cores of our cells, it’s worth bearing in mind that there’s no magic involved, and that we’re constantly getting better at understanding how these processes work.
Which, I expect, is why Drexler is so fascinated by them: once we know how the body’s nanomachines work, we’ll be properly equipped to start building new ones.
