名詞

gene (plural genes)

1. (genetics) A theoretical unit of heredity of living organisms which may take several values and (in principle) predetermines a precise trait of an organism's form (phenotype), such as hair color.

   Coordinate term: phene

   Near-synonym: cistron (often synonymous)

   • 2013 June 21, Karen McVeigh, “US rules human genes can't be patented”, in The Guardian Weekly, volume 189, number 2, page 10:

     The US supreme court has ruled unanimously that natural human genes cannot be patented, a decision that scientists and civil rights campaigners said removed a major barrier to patient care and medical innovation.

2. (molecular biology) A segment of DNA or RNA from a cell's or an organism's genome, that may take several forms and thus parameterizes a phenomenon, such as (often) the structure of a protein.

   Holonym: locus

   A change in a gene is reflected in the protein or RNA molecule that it codes for.

   • 2019, Bill Bryson, The Body: A Guide for Occupants, Black Swan (2020), page 7:

     A length of DNA is divided into segments called chromosomes and shorter individual units called genes.

   • 2025, The Economist staff, “Primer 1: Nucleic acids and proteins”, in The Economist (Biology Primers series)‎, retrieved 18 October 2025:

     One way to define a gene (there are many, and they are not all equivalent) is as the bit of DNA that contains the information needed to make a specific protein or a functional RNA molecule.

使用する際の注意点

In the simplest case and in principle, a gene as a locus (or part of one) is supposed to be the physical reality corresponding to the theoretical gene as a unit of heredity; in practice, things are far more complicated and confused, which is well known and acknowledged. However, these questions are the subject of still very active scientific research, as well as the topic of both scientific and philosophical questions, especially on the real compatibility between both senses of the term.
