clone

 [klōn]
1. the genetically identical progeny produced by the natural or artificial asexual reproduction of a single organism, cell, or gene, such as plant cuttings, a cell culture descended from a single cell, or genes reproduced by recombinant DNA technology.
2. to establish or produce such a line of progeny. adj., adj clo´nal.

In 1997 a lamb was cloned in the United Kingdom, and in 2001 a cat was cloned in Texas. The idea of cloning animals remains a controversial subject that is being discussed by ethicists.

clone

clone

Etymology: Gk, klon, a plant cutting
a group of genetically identical cells or organisms derived from a single common cell or organism through mitosis. clonal, adj.

clone

A population of cells derived from a single parent cell and thus genetically identical; genetic differences in clonal population may arise from random spontaneous mutations during cell growth

clone

1. A perfect copy, or a population of perfect copies, of any organism. Cloning occurs when an organism reproduces non-sexually, so that the genetic content (genome) of each is identical.
2. A number of identical cells derived from a single cell by repetitive division.
3. A perfect copy, or any number of copies, of any DNA sequence, such as a gene, or any other nucleotide sequence.

clone

  1. any of two or more individuals with identical genetic makeup produced from one parent by ASEXUAL REPRODUCTION. Examples of clones are daughter plants produced by strawberry RUNNERS, and whole plants produced by tissue culture.
  2. the identical individuals produced by the splitting of a young embryo.
  3. to produce a set of identical DNA molecules or identical individuals from a single DNA molecule or single cell, as in GENETIC ENGINEERING.

Clone

A cell or organism derived through asexual (without sex) reproduction containing the identical genetic information of the parent cell or organism.

clone

progeny derived from a single cell by asexual reproduction

clone

1. the genetically identical or closely similar progeny produced by the natural or artificial asexual reproduction of a single organism, cell or gene, e.g. plant cuttings, a cell culture descended from a single cell, or genes reproduced by recombinant DNA technology.
2. to establish or produce such a line of progeny.
