DNA Complexity - How Does DNA Reveal Design?
Before we can discuss DNA complexity, it is important to understand what DNA is. The DNA Double Helix (deoxyribonucleic acid) is a double-stranded molecule that is twisted into a helix like a spiral staircase. Each strand is comprised of a sugar-phosphate backbone and numerous base chemicals attached in pairs. The four bases that make up the stairs in the spiraling staircase are adenine (A), thymine (T), cytosine (C) and guanine (G). These stairs act as the "letters" in the genetic alphabet, combining into complex sequences to form the words, sentences and paragraphs that act as instructions to guide the formation and functioning of the host cell. Maybe even more appropriately, the A, T, C and G in the genetic code of the DNA molecule can be compared to the "0" and "1" in the binary code of computer software. Like software to a computer, the DNA code is a genetic language that communicates information to the organic cell.
DNA Complexity - Microscopic Marvel
The DNA code, like a floppy disk of binary code, is quite simple in its basic paired structure. However, it's the sequencing and functioning of that code that's enormously complex. Through recent technologies like x-ray crystallography, we now know that the cell is not a "blob of protoplasm", but rather a microscopic marvel that is more complex than the space shuttle. The cell is very complicated, using vast numbers of phenomenally precise DNA instructions to control its every function.
Although DNA code is remarkably complex, it's the information translation system connected to that code that really baffles science. Like any language, letters and words mean nothing outside the language convention used to give those letters and words meaning. This is modern information theory at its core. A simple binary example of information theory is the "Midnight Ride of Paul Revere." In that famous story, Mr. Revere asks a friend to put one light in the window of the North Church if the British came by land, and two lights if they came by sea. Without a shared language convention between Paul Revere and his friend, that simple communication effort would mean nothing. Well, take that simple example and multiply by a factor containing many zeros.
We now know that the DNA molecule is an intricate message system. To claim that DNA arose by random material forces is to say that information can arise by random material forces!
