Here's a great video at Telic Thoughts that gives a molecule-eye view of DNA packaging and replication. The processes are truly astonishing. Please resist the temptation to think that what you see is all a product of intentional design by an intelligent designer. We know that the appearance of design is purely an illusion and that natural forces acting blindly managed to engineer...oops..., design...oops..., evolve this apparatus completely by accident. We know this because we know there is no intelligent designer, and we know there's no intelligent designer because we can't find an example of something in the natural world that's intelligently designed. Or something like that.
