DNA Double Helix: A Recent Discovery of Enormous Complexity
The DNA Double Helix is one of the greatest scientific discoveries of all time. First described by James Watson and Francis Crick in 1953, DNA is the famous molecule of genetics that establishes each organism's physical characteristics. It wasn't until mid-2001, that the Human Genome Project and Celera Genomics jointly presented the true nature and complexity of the digital code inherent in DNA. We now understand that each human DNA molecule is comprised of chemical bases arranged in approximately 3 billion precise sequences. Even the DNA molecule for the single-celled bacterium, E. coli, contains enough information to fill all the books in any of the world's largest libraries.

DNA Double Helix: The "Basics"
DNA (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.

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. Many scientists argue that the chemical building blocks of the DNA molecule can be explained by natural evolutionary processes. However, they must realize that the material base of a message is completely independent of the information transmitted. Thus, the chemical building blocks have nothing to do with the origin of the complex message. As a simple illustration, the information content of the clause "nature was designed" has nothing to do with the writing material used, whether ink, paint, chalk or crayon. In fact, the clause can be written in binary code, Morse code or smoke signals, but the message remains the same, independent of the medium. There is obviously no relationship between the information and the material base used to transmit it. Some current theories argue that self-organizing properties within the base chemicals themselves created the information in the first DNA molecule. Others argue that external self-organizing forces created the first DNA molecule. However, all of these theories must hold to the illogical conclusion that the material used to transmit the information also produced the information itself. Contrary to the current theories of evolutionary scientists, the information contained within the genetic code must be entirely independent of the chemical makeup of the DNA molecule.

DNA Double Helix: Its Existence Alone Defeats any Theory of Evolution
The scientific reality of the DNA double helix can single-handedly defeat any theory that assumes life arose from non-life through materialistic forces. Evolution theory has convinced many people that the design in our world is merely "apparent" -- just the result of random, natural processes. However, with the discovery, mapping and sequencing of the DNA molecule, we now understand that organic life is based on vastly complex information code, and such information cannot be created or interpreted without a Master Designer at the cosmic keyboard.

Gobsmacked....indeed I am. The wonder of it all. This is our God. A very interesting and a very educational post.

I have just now read it and been caused to marvel. As the bible says...."what is man that thou art mindfull of him, or the son of man that thou didst visit him"

What is man? Man is the unique being, the Lord of God's creation. He was made such by Almighty God. Adam transgressed.....we recall the sad story.......But a second Adam to the fight and to the rescue came. "God was in Christ....reconciling the world unto himself"

And you know? What ever the first Adam lost, Christ has found. We who are in Jesus are not impoverished as a result of Adam's fall We are more in Jesus than ever we were in Adam....Amen? We have much, wonderfully much in Adam, but in Jesus we have so much more. Hallelujah

Let us rise up in Jesus today, let us recognise the greatness of our stature in Jesus. May we go forth in His Name....each day....aware that God is with us.
The God of Jacob is our Refuge....underneath and round about us are the everlasting arms.

Thankyou Jesus. Amen Amen

DNA has always been real interesting iv seen alot of videos showing its connection to God and even to his word so its good to see this here thanks for posting it.

We know that there are right-handed and left-handed gloves. This is also true of amino acid molecules. Of some 100 known amino acids, only 20 are used in proteins, and all are left-handed ones. When scientists make amino acids in laboratories, in imitation of what they feel possibly occurred in a prebiotic soup, they find an equal number of right-handed and left-handed molecules. “This kind of 50-50 distribution,” reports The New York Times, is “not characteristic of life, which depends on left-handed amino acids alone.” Why living organisms are made up of only left-handed amino acids is “a great mystery.” Even amino acids found in meteorites “showed excesses of left-handed forms.”

Dr. Jeffrey L. Bada, professor of Marine Chemistry and who studies problems involving the origin of life, said that “some influence outside the earth might have played some role in determining the handedness of biological amino acids.”

British astronomer Sir Fred Hoyle (1915-2001) spent decades studying the universe and life in it, even espousing that life on earth arrived from outer space. Lecturing at the California Institute of Technology, he discussed the order of amino acids in proteins.

“The big problem in biology,” Hoyle said in 1981, “isn’t so much the rather crude fact that a protein consists of a chain of amino acids linked together in a certain way, but that the explicit ordering of the amino acids endows the chain with remarkable properties . . . If amino acids were linked at random, there would be a vast number of arrangements that would be useless in serving the purposes of a living cell. When you consider that a typical enzyme has a chain of perhaps 200 links and that there are 20 possibilities for each link, it’s easy to see that the number of useless arrangements is enormous, more than the number of atoms in all the galaxies visible in the largest telescopes. This is for one enzyme, and there are upwards of 2000 of them, mainly serving very different purposes. So how did the situation get to where we find it to be?”

Hoyle added: “Rather than accept the fantastically small probability of life having arisen through the blind forces of nature, it seemed better to suppose that the origin of life was a deliberate intellectual act.”

Professor Michael J. Behe, who serves as professor at Lehigh University in Pennsylvania, stated: “To a person who does not feel obliged to restrict his search to unintelligent causes, the straightforward conclusion is that many biochemical systems were designed. They were designed not by the laws of nature, not by chance and necessity; rather, they were planned. . . . Life on earth at its most fundamental level, in its most critical components, is the product of intelligent activity.”

Proteins are the most abundant macromolecules found in cells. It has been estimated that they account for more than half the dry weight of most organisms! Proteins are made up of smaller building blocks called amino acids. Proteins have many functions. For example, there is hemoglobin, a protein found in red blood cells, which transports oxygen throughout your body. Then there are antibodies, which help your body to ward off disease. Other proteins, such as insulin, help you to metabolize foods as well as regulate various cellular functions. In all, there may be thousands of different kinds of proteins in your body. There may be hundreds within just a single cell !

Each protein carries out a specific function that is determined by its DNA gene. But how is the genetic information in a DNA gene decoded so that a particular protein is made? The genetic information stored in the DNA must first be transferred from the nucleus of the cell into the cytoplasm, where the ribosomes, or protein-producing factories, are located. This transfer is accomplished by means of an intermediary called ribonucleic acid (RNA). The ribosomes in the cytoplasm “read” the RNA instructions and assemble the proper sequence of amino acids to form a particular protein. Thus, there exists an interdependent relationship between DNA, RNA, and the formation of proteins.

Michael Behe, in an interview with Awake ! magazine, said: "The conclusion of design is not due to ignorance. It’s not due to what we don’t know; it’s due to what we do know. When Darwin published his book The Origin of Species 150 years ago, life seemed simple. Scientists thought that the cell was so simple that it might just spontaneously bubble up from sea mud. But since then, science has discovered that cells are enormously complex, much more complex than the machinery of our 21st-century world. That functional complexity bespeaks purposeful design."
