DNA or Deoxyribonucleic acid is a type of nucleic acid. It is present in all living cells of bacteria, trees, dogs, cats and human. Some viruses also contain DNA. DNA was discovered in 1868 by the German biochemist, Friedrich Miescher who called it nuclein. Chemical analysis of highly purified DNA have shown that it is made of four kinds of monomeric building blocks, each of which contains three types of molecules: (i) Phosphoric acid,  (ii) Pentose sugar, and (iii) Organic bases. As you can observe on the diagrams of DNA, the DNA molecule actually consists of two such chains that spiral around an imaginary axis to form a double helix (spiral).  Nucleic acid molecules are incredibly complex, containing the code that guarantees the accurate ordering of the 20 amino acids in all proteins made by living cells.  Surprisingly though there are only a few different nucleotides: only four different nucleotide units comprise DNA, the nucleic acid of interest to the genealogist.

The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. The full name of DNA, deoxyribonucleic acid, gives you the name of the sugar present – deoxyribose. It is a modified form of another sugar called ribose. I’m going to give you the structure of that first, because you will need it later anyway. Ribose is the sugar in the backbone of RNA, ribonucleic acid. Each strand of DNA is made of chemicals called bases. Do not confuse these with the bases you meet when you study acids and alkalis in chemistry. There are four different types of bases, shown as A, T, C and G in the diagram.

Adenine (“A”) and Thymine (“T”) each have one donor and one acceptor, whereas Cytosine (“C”) has one donor and two acceptors, and Guanine (“G”) has one acceptor and two donors. With further look at the diagram, you’ll get to know the deeper details of the structures of DNA.
