Natural Competence
In microbiology, genetics, cell biology and molecular biology, competence is the ability of a cell to take up extracellular ("naked") DNA from its environment. Competence may be differentiated between natural competence, a genetically specified ability of bacteria which is thought to occur under natural conditions as well as in the laboratory, and induced or artificial competence, which arises when cells in laboratory cultures are treated to make them transiently permeable to DNA. This article primarily deals with natural competence in bacteria. Information about artificial competence is provided in the article Transformation (genetics).

Famous quotes containing the words natural and/or competence:
“Of all natural forces, vitality is the incommunicable one.... Vitality never “takes.” You have it or you haven’t it, like health or brown eyes or a baritone voice.”
—F. Scott Fitzgerald (1896–1940)
“Witness the American ideal: the Self-Made Man. But there is no such person. If we can stand on our own two feet, it is because others have raised us up. If, as adults, we can lay claim to competence and compassion, it only means that other human beings have been willing and enabled to commit their competence and compassion to us—through infancy, childhood, and adolescence, right up to this very moment.”
—Urie Bronfenbrenner (20th century)
