PZ Meyers posted a neat animation on his weblog “Pharyngula” the other day. The first part shows DNA coiling and packaging; the second part DNA replication.
I especially like these because they portray the complexity and beauty of these ubiquitous cellular processes, yet also exhibit their chemical, mechanical nature. We tend to personify biological phenomena (“the DNA unwinds, then adds complementary base pairs to each strand”); it’s easy to forget that these are essentially mechanical, step-by-step processes.
And yet they’re still beautiful.
