DNA

Genes are made from a long [|molecule] called [|DNA], which is copied and   inherited    across generations. DNA is made of [|simple units] that line up in a particular order within this long molecule. The order of these units carries   genetic information   , similar to how the order of letters on a page carries information. The language used by DNA is called the [|genetic code], which allows the genetic machinery to read the information in the genes in triplet sets of [|codons]. This information is the instructions for constructing and operating a living organism.

 * [|Nucleic Acid]** - Type of essential Organic Compund the carries information and is composed of monomers called Nucleotides. Nucleic Acids are made up of the elements Carbon, Hydrogen, Oxygen, Phosphorous and Nitrogen. CHOPN
 * [|DNA]** -    DeoxyriboNucleic Acid     - The Blue Print of Life - contains all of the information to make each of us.
 * [|Nucleotide]** - The monomers that make up a    Nucleic Acid     . Each nucleotide is composed of a 5-C    sugar   , a Phosphate group and a Nitrogen   base.
 * [|Double helix]** - The "twisted    ladder     " structure of DNA as proposed by  Watson and Crick.
 * Pyrimidine** - Nitrogen base that has a single Carbon ring. Thymine and Cytosine are Pyrimidines.
 * Purine** - Nitrogen base that has a double Carbon ring. Guanine and Adenine are Purines.
 * [|Purines vs Pyrimidines]**
 * [|Base Pairing Rule]** - Simple Rule in which Adenine (A) can only pair with Thymine (T) and Guanine (G) can only pair with Cytosine (C). This ensures that a Purine always #|bonds with a Pyrimidine. This makes each "rung" of the Double Helix 3 Carbon rings wide.
