clone
n 1: a person who is almost identical to another [synonym: {ringer},

from a single cell or individual by some kind of asexual
reproduction [synonym: {clone}, {clon}]

an organism by a non-sexual process of reproduction.
[WordNet 1.5]

2. (Microbiol.) to grow colonies of a microorganism by
spreading a suspension of the microorganism onto a solid
growth medium (such as in a Petri dish), at a
concentration such that individual colonies will grow from
single cells sufficiently well separated from other
colonies so that pure cultures derived from a single
organism can be isolated.
[WordNet 1.5]

3. (Biochem.) to make large quantities of a segment of DNA by
inserting it, using biochemical techniques, into the DNA
of a microorganism, and growing that microorganism in
large numbers; as, to clone the gene for growth hormone.
[PJC]


clone \clone\ (kl[=o]n), n.
1. (Biol.) a group of organisms derived from a single
individual by some kind of asexual reproduction; -- used
mostly of microorganisms such as bacteria and yeast.

Syn: clon.
[WordNet 1.5]

2. (Biol.) an individual organism containing a genetic
complement identical to that of another organism, produced
by using the genetic material from the second animal in a
non-sexual reproduction process.
[PJC]

3. something virtually identical to another object.
