DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide.
Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. The nitrogenous base is the part of the nucleotide that carries genetic information, so the words "nucleotide" and "base" are often used interchangeably. The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymineoften abbreviated as A, C, G, and T, the letters of the genetic alphabet.
A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next. DNA is often said to have a sugar and phosphate "backbone."
Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in "base pairs," or bpthat is, the number of rungs in the ladder. Sometimes, this unit of measurement is shortened simply to "bases."

You just reinforced what I just said with pictures. Thanks.
The DNA “code”is made up of the four bases. The deoxyribo backbone is the structural part of the molecule.
Pretty simple when you see it, isn’t it?
I have some questions for you since you seem to believe you are one of the high Priests of cerebral cortex worship.
Where did the first spark of energy come from? Why has science stopped researching the paranormal and spiritual aspects of the brain? Why do they call it a scientific fact and then change it when new evidence come out?
Do you have complete unfailing faith in this centuries research or will you convert when the next "evidence" replaces this "evidence"? If you are a true believer you must decide now or you are ignorant, a fool, an infidel and heretic to your peers. You must read every science book written by man and believe it all without fail....trust. Should I subject myself to all this and just have faith that it will never change?
Why don't you tell us all now, ...is this science finished? Will it never change? Is it rock solid for the ages? Should we all start worshiping at the altar of your brothers cerebral cortex and bow down to their wisdom or wait until the next century?
You must have all the answers...scientists are so smart. Other scientist tell us so and besides, they call us all stupid, so we really must be right? Kind of like the totalitarian Priest used to do before they threw people out of bell towers.
Please save us from a fate worse than death. Tell us what to do to save ourselves from the scientific self made God's before they get us.
