clone

/ kləʊn /

noun

1. a group of organisms or cells of the same genetic constitution that are descended from a common ancestor by asexual reproduction, as by cuttings, grafting, etc, in plants

clone

/ klōn /

Noun

1. A cell, group of cells, or organism that is produced asexually from and is genetically identical to a single ancestor. The cells of an individual plant or animal, except for gametes and some cells of the immune system, are clones because they all descend from a single fertilized cell and are genetically identical. A clone may be produced by fission, in the case of single-celled organisms, by budding, as in the hydra, or in the laboratory by putting the nucleus of a diploid cell into an egg that has had its nucleus removed. Some plants can produce clones from horizontal stems, such as runners. Clones of other cells and some plants and animals can also be produced in a laboratory.
2. See also therapeutic cloning
3. A copy of a sequence of DNA, as from a gene, that is produced by genetic engineering. The clone is then transplanted into the nucleus of a cell from which genetic material has been removed.

Verb

1. To produce or grow a cell, group of cells, or organism from a single original cell.
2. To make identical copies of a DNA sequence.
3. See more at genetic engineering

clone

1. A living system that is genetically identical to its ancestor (that is, it has exactly the same DNA molecules ). Because each cell contains the DNA molecules that characterize an individual, it is, in principle, possible to replicate, or reproduce, complex living systems in the laboratory.

Notes

There is a major debate on the ethical aspects ( see bioethics ) of cloning, especially as applied to human beings. Therapeutic cloning involves the placing of adult DNA in an egg for the express purpose of creating stem cells for medical purposes. Reproductive cloning involves the placement of adult DNA into an egg and the implantation of the egg into a uterus for the purpose of creating a viable fetus .

The first cloned mammal, a sheep named Dolly , was born in Scotland in 1996. DNA from an adult donor was placed into an egg , which was then implanted in the uterus of another sheep. Since that time, mice, cows, and pigs have been cloned.

Clone is often used informally to indicate a close copy or resemblance: “This new computer is a clone of the IBM model.”
