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:
“Knowledge has two extremes. The first is the pure natural ignorance in which all men find themselves at birth. The other extreme is that reached by great minds, who, having run through all that men can know, find they know nothing, and come back again to that same natural ignorance from which they set out; this is a learned ignorance which is conscious of itself.”
—Blaise Pascal (1623–1662)
“I duly acknowledge that I have gone through a long life, with fewer circumstances of affliction than are the lot of most men. Uninterrupted health, a competence for every reasonable want, usefulness to my fellow-citizens, a good portion of their esteem, no complaint against the world which has sufficiently honored me, and above all, a family which has blessed me by their affections, and never by their conduct given me a moment’s pain.”
—Thomas Jefferson (1743–1826)
