Exposure to a
mutagen is the means by which the anthropomorphic
animals in Teenage Mutant Ninja Turtles, for example, gained their forms.
Full article >>>MutagenIn
biology, a
mutagen (Latin, literally
origin of change) is an agent that changes the genetic information (usually
DNA) of an
organism and thus increases the number of
mutations above the natural background level.
Full article >>>The production of either random or specific
mutations in a piece of
cloned
DNA. Typically, the
DNA will then be reintroduced into a
cell or an
organism to assess the results of the
mutagenesis.
