\chapter{DNA Structure}
\ac{DNA} is well known in the form of a double helix. A double helix consists, as the name suggestes, of two single helix. Each of them consists of two main components: the Suggar Phosphat backbone, which is irelavant for this Paper and the Bases. The arrangement of Bases represents the Information stored in the \acs{DNA}. A base is an organic molecule, they are called Nucleotides. %Nucleotides have special attributes and influence other Nucleotides in the \acs{DNA} Sequence

\section{Nucleotides}
For this paper, nucleotides are the most important parts of the \acs{DNA}. A Nucleotide can have one of four forms: it can be either adenine, thymine, guanine or cytosine. Each of them got a Counterpart on the helix, to be more explicit: adenine can only bond with thymine, guanine can only bond with cytosine. This means with the content of one helix, the other one can be determined by ``inverting'' the first. The counterpart for e.g.: adenine, guanine, adenine would be: thymine, cytosine, thymine. For the sake of simplicity, one does not write out the full name of each nucleotide but only use its initial: AGA in one Helix, TCT in the other.
