DNA
Deoxyribonucleic acid. The chemical building block of the genetic information in the cell from which genes are composed; it specifies the characteristics of most living organisms. DNA consists of a long molecule of repeating units (each unit containing deoxyribose (a sugar), a phosphoric acid and a base) joined together in a particular order. DNA is usually found as two complementary strands twisted into the shape of a double helix.
DNA code
The sequence (order) of DNA bases in a gene, which make up the instructions for a particular characteristic of the organism. [JIC]
