According to the official Guidelines for Human Gene Nomenclature, a gene is defined as a DNA segment that contributes to phenotype/function. In the absence of demonstrated function a gene may be characterized by sequence, transcription or homology.. Genes are composed of DNA, a molecule in the memorable shape of a double helix, a spiral ladder. Each rung of the spiral ladder consists of two paired chemicals called bases.
Genes and proteins are written in different languages.. Genes are encoded within DNA, which are made of nucleotides, while proteins are constructed out of amino acids. In order for a biological cell to make proteins, the genetic information from DNA has to be translated.
