DNA: DNA molecules hold the genetic informaion required for the maintenance and function of most living cells. A DNA molecule is formed by two chemical strands coiled around each other to form a double helix. The DNA does this by copying itself into similar RNA structures. The DNA uncoils inteslf, one strand forming the template on which RNA is formed.The resultant message RNA is passed out of the nucleus, into the surrounding cytoplasm. Here it forms a template for the sysnthesis of required proteans such as enzymes.

DNA is able to replicate itself, it does this by seperating its helix strands, each providing a template for the synthesis of a new complementary strand. The strands combine forming two pairs of DNA helix. The enzymes are large molecules consisting entirely or mainly of protein. It is these that act as catalysts for biochemical reactions. the shape of the enzyme molecule determins the specific reaction that it catalyzes. A DNA molecule is composed of four sub-units known as nucleotides. Each nucleotide consists of 3 parts: a sugar called deoxyribose, a phosphate group and an organic base.

The sugar and phosphate groups form the backbone of the DNA helix, and are the same for all nucleotides. Only the bases of the nucleotides differ however, being either Adenine(A), Cytosine(C), Guanine(G), or Thymine(T). If a spiral ladder analogy is used, the sides of the ladder are formed by the alternating sugar and phosphate groups of the nucleotide. The rungs of the ladder being the links between organic bases with A always linked to T and C always linked to G. Because of the chemical structure of the chemical bases, neither A nor T can combine with C or G. Therefore, should the DNA unzip down the middle, each base would combine with its opposite number from the free nucleotides floating freely in the nucleus. Each molecule half would act as the template for the construction of a copy - the process involved in creating RNA.

The cell is able to use this of sequenced data to manufacture the protein molecules that it needs to function. Genetic information is described by the sequences of the bases. The four bases, ACTG form the alphabet and are arranged into words of three letters called condons. The resulting 64 possible combinations of sequenced data are used by the cell to manufacture the protein molecules that a cell needs in order to function.
