pictures of DNA molecules: Various DNA double helix.

DNA was originally discovered in 1869 by Johann Friedrich Miescher who described the molecule as 'nuclein', since recognised as DNA and RNA. Alfred Hershey and Martha Chase studied viral replication in bacteria and saw that DNA was the genetic material involved. In 1953 James Watson and Francis Crick discovered the three dimensional double helix of DNA.

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.

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).
