clone

clone (klōn)

1. the genetically identical 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.clo´nal

clone (kln)

n.

1. A cell, group of cells, or organism descended from and genetically identical to a single common ancestor, such as a bacterial colony whose members arose from a single original cell.

2. An organism descended asexually from a single ancestor, such as a plant produced by layering or a polyp produced by budding.

3. A DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques.

v.

1. To make multiple identical copies of a DNA sequence.

2. To create or propagate an organism from a clone cell:

3. To establish and maintain pure lineages of a cell under laboratory conditions.

4. To reproduce or propagate asexually.

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.

2. to establish or produce such a line of progeny.

clone bank

clone site

the site where insertion of the transfer DNA segment may occur on a cloning vector.

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
