Natural Competence

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:

    For my own part, I commonly attend more to nature than to man, but any affecting human event may blind our eyes to natural objects. I was so absorbed in him as to be surprised whenever I detected the routine of the natural world surviving still, or met persons going about their affairs indifferent.
    Henry David Thoreau (1817–1862)

    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)
