gene
(jēn)n.
A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and is transcribed into an RNA molecule that may function directly or be translated into an amino acid chain. Genes undergo mutation when their DNA sequences change.
[German Gen, from gen-, begetting, in Greek words (such as genos, race, offspring); see genə- in Indo-European roots.]

gene
(dʒiːn)n
(Genetics) a unit of heredity composed of DNA occupying a fixed position on a chromosome (some viral genes are composed of RNA). A gene may determine a characteristic of an individual by specifying a polypeptide chain that forms a protein or part of a protein (structural gene); or encode an RNA molecule; or regulate the operation of other genes or repress such operation. See also operon
[C20: from German Gen, shortened from Pangen; see pan-, -gen]

gene
(dʒin)n.
the basic physical unit of heredity; a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein, leads to the expression of hereditary character.
[1911; < German Gen (1909), appar. independent use of -gen -gen; introduced by Danish geneticist Wilhelm Latin. Johannsen (1857–1927)]

gene
(jēn) A segment of DNA, occupying a specific place on a chromosome, that is the basic unit of heredity. Genes act by directing the synthesis of proteins, which are the main components of cells and are the catalysts of all cellular processes. Physical traits, such as the shape of a plant leaf, the coloration of an animal's coat, and the texture of a person's hair, are all determined by genes. See also dominant, recessive. See Notes at DNA, Mendel.
Did You Know? What makes a human different from a chimpanzee? Much of the answer lies in the genes, the basic units of heredity. Each gene is a specific segment of DNA, occupying a fixed place on a chromosome. Genes contain the chemical information needed to create different kinds of proteins. These proteins are used to repair cells and make new ones. The kinds of proteins, the amounts, and the order in which they are made all help determine how one type of cell differs from another and, ultimately, how one species of organism differs from another. Just how different are the genes making up different life forms? In the case of the human and the chimp, not much: about 98 percent of the DNA in a chimpanzee cell is identical to the DNA in a human cell. Because of this close similarity, scientists think that it is the sequence of genes, as well as the types of genes themselves, that account for most of the differences between the two species. However, not all differences between species can be explained by gene differences alone. How closely matching sets of genes can belong to entirely different species is one of the great mysteries of modern biology.
