'''Deoxyribonucleic acid''' (DNA) is a molecular [[polymer]] formed of [[nucleotide|deoxyribonucleotides]]. Most commonly as a double-stranded [[helix]] comprising two complimentary molecules held together by hydrogen bonds, this is commonly called "dsDNA" (double-stranded DNA)<ref>Single-stranded DNAs (ssDNA) do exist in certain [[bacteriophage]]s, however they cannot be replicated without first creating the complimentary strand to use as a template.</ref>. The [[nucleotide]]s which are the "building blocks" of DNA have three main parts: A nitrogenous base (the "letters" in the sequence), a [[sugar]], and a [[phosphate]] group. When nucleotides are joined into DNA strands, they form a chain with the phosphate group of one nucleotide binding to the ribose of the next.
'''Deoxyribonucleic acid''' (DNA) is a chemical inside [[cell]]s which carries the hereditary information. It is a molecular [[polymer]] formed of [[nucleotide|deoxyribonucleotides]]. All organisms use DNA as their hereditary material. [[Offspring]] of [[sexually reproducing|Sexual_reproduction]] [[organisms|Organism]] contain DNA from both parents.

DNA strands "compliment" each other by having compatible sequences, allowing the bases on one strand to form bonds with the bases on the other strand. There are four nitrogenous bases, Adenonine (A), Cytosine (C), Guanine (G), and Thymine (T). Under the base pairing rules, A pairs with T and G pairs with C.
