What enables a long chain of linked amino acids to perform highly specific molecular functions with machine-like precision?
Design motifs such as four-bar linkages and control systems must meet exacting requirements whether implemented in a space shuttle or a fish.
Take a tour of molecular machines working in the cell and see what new things scientists have found out about them.
There are various types of flagella, but all function like a rotary engine made by humans. Even non-ID scientists marvel at the complexity of these machines.
If one visualizes the recoil action of large guns on ships as they fire, that is perhaps what the EA (export apparatus) is doing for the T3SS.
