Webster's 1913 Dictionary
  1. \Mu*ta"tion\, n. [L. mutatio, fr. mutare to change: cf.
    F. mutation. See {Mutable}.]
    Change; alteration, either in form or qualities.
          The vicissitude or mutations in the superior globe are
          no fit matter for this present argument. --Bacon.
  2. \Mu*ta"tion\, n.
    1. (Biol.) Gradual definitely tending variation, such as may
       be observed in a group of organisms in the fossils of
       successive geological levels.
    2. (Biol.)
       (a) As now employed (first by de Vries), a sudden
           variation (the offspring differing from its parents in
           some well-marked character or characters) as
           distinguished from a gradual variations in which the
           new characters become fully developed only in the
           course of many generations. The occurrence of
           mutations, and the hereditary transmission, under some
           conditions, of the characters so appearing, are
           well-established facts; whether the process has played
           an important part in the evolution of the existing
           species and other groups of organisms is a disputed
       (b) The result of the above process; a suddenly produced
Medical Dictionary
 Definition: Any change in the DNA of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment. Mutations can be harmful, beneficial, or have no effect. If they occur in cells that make eggs or sperm, they can be inherited; if mutations occur in other types of cells, they are not inherited. Certain mutations may lead to cancer or other diseases.
Biology Dictionary
 Definition: A heritable change in DNA sequence resulting from mutagens. Various types of mutations include frame-shift mutations, missense mutations, and nonsense mutations.
  1. An alteration in DNA structure or sequence of a gene. (See Point mutation)
  2. Any heritable change in DNA sequence.
  3. an alteration of the genetic material.
