About DNA

DNA (deoxyribonucleic acid) is the primary genetic material in all living organisms - a molecule composed of two complementary strands that are wound around each other in a double helix formation. The strands are connected by base pairs that look like rungs in a ladder. Each base will pair with only one other: adenine (A) pairs with thymine (T), guanine (G) pairs with cytosine (C). The sequence of each single strand can therefore be deduced by the identity of its partner.

Genes are sections of DNA that code for a defined biochemical function, usually the production of a protein. The DNA of an organism may contain anywhere from a dozen genes, as in a virus, to tens of thousands of genes in higher organisms like humans. The structure of a protein determines its function. The sequence of bases in a given gene determines the structure of a protein. Thus the genetic code determines what proteins an organism can make and what those proteins can do. It is estimated that only 1-3% of the DNA in our cells codes for genes; the rest may be used as a decoy to absorb mutations that could otherwise damage vital genes.
