Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

  • n. A unit of heredity; a segment of DNA or RNA that is transmitted from one generation to the next, and that carries genetic information such as the sequence of amino acids for a protein.

Etymologies

(American Heritage® Dictionary of the English Language, Fourth Edition)
From German Gen, coined by Wilhelm Ludvig Johannsen from Ancient Greek γενεά (geneá, "generation, descent") from the aorist infinitive of γίγνομαι (gígnomai, "I come into being"). (Wiktionary)

  • Of course, philosophers do not deny that biologists use the term gene, but many philosophers believe gene is a dummy term, a placeholder for many different concepts.

    Molecular Genetics

  • In fact, philosophers have often been frustrated by the tendency of biologists to define and use the term gene in a number of contradictory ways in one and the same textbook.

    Molecular Genetics

  • Gene skeptics such as Burian, Portin, and Fogle claim that the term gene has outlived its usefulness.

    Molecular Genetics

  • Weber (2005) examines the evolution of the gene concept by tracing changes in the reference of the term gene through the history of genetics.

    Molecular Genetics

  • If the globin gene is damaged (marked by an arrow) it may, for example, lead to the formation of a larger than normal exon during splicing (B), or to the formation of a completely new exon (C).
