In Which I Explain DNA Structure

     DNA is what makes us humans up. Our incredible bodies are made up of seemingly simple structures. To begin explaining what the structure of DNA is, I will show you a very familiar ladder looking picture.

     At this point in time, I would like to direct your attention to the thing labeled base pair. A base pair will always be made up of the four letters G,T,C, and A (Green-Cat, Ass-Tan). A stands for Adenine, T stands for Thymine, G stands for Guanine and C stands for Cytosine.  In my little rhyme, I specifically paired G with C and A with T. These are the only things that can be paired together, but there is an infinite number of combinations within the helix that bases can repeat and be lined up to produce proteins that create    characteristics. 

     Nucleotides are groups made of sugars and phosphates joined to a single base that are connected through covalent bonds and to make up a chain. This chain is paired to another (by matching appropriate bases) to make a base pair through hydrogen bonding in order to make the double helix you know and love. 

     This 'simple' process rebuilds and rebuilds upon itself to make human beings... which is the tightest thing ever. In order to replicate itself, The DNA will go through a process and unzip to a certain point, leaving the nucleotides alone again. But there is good news! Newer nucleotides and bases will be attracted to the old strands and connect to them through hydrogen bonding. They continue to unzip and reconnect almost infinitely, creating life and sequences! This picture will easier explain the replicating method of DNA.
