clone
n 1: a person who is almost identical to another [synonym: {ringer},
{dead ringer}, {clone}]
2: a group of genetically identical cells or organisms derived
from a single cell or individual by some kind of asexual
reproduction [synonym: {clone}, {clon}]
3: an unauthorized copy or imitation [synonym: {knockoff}, {clone}]
v 1: make multiple identical copies of; "people can clone a

clone \clone\ v. t.
1. (Biol.) to make a clone from; to make identical copies of
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.

E.g. "PC clone": a PC-BUS/{ISA}, {EISA}, {VESA}, or {PCI}
compatible {x86}-based {microcomputer} (this use is sometimes
misspelled "klone" or "PClone"). These invariably have much more
bang per buck than the {IB PCM} they resemble.

E.g. "Unix clone": An {operating system} designed to deliver a
{Unix}-like environment without Unix licence fees or with
additional "mission-critical" features such as support for
{real-time} programming.

  • Human Cloning - Center for Genetics and Society
    Human reproductive cloning – producing a genetic copy of an existing person using somatic cell nuclear transfer – has never been done Many scientists believe that it can never be safe In opinion polls, , overwhelming majorities consistently reject its use The U S has no federal law on human reproductive cloning, but several states, dozens of countries, and international agreements
  • Reproductive Cloning Arguments Pro and Con
    If you cloned yourself, the resulting child would be neither your son or daughter nor your twin brother or sister, but a new category of human being: your clone The great majority of people have an intuitive sense that human beings should not be cloned Arguments offered for and against reproductive cloning are given below
  • Human Cloning Policies - Center for Genetics and Society
    Estimates as to when a human clone might be born, if no action is taken to prevent it, range from immediately to five or ten years Research Cloning Some countries, notably France, Germany, and Canada, explicitly ban the creation of clonal embryos
  • Reproductive Cloning Basic Science - Center for Genetics and Society
