Cloning is the process of creating an identical copy of an original. A clone in the biological sense, therefore, is a single cell (like bacteria, lymphocytes etc.) or multi-cellular organism that has been directly copied from and is therefore genetically identical to another living organism. Sometimes this term can refer to "natural" clones made either when an organism reproduces asexually or when two genetically identical individuals are produced by chance (as with identical twins), but in common parlance, a clone is an identical copy created intentionally. (See also: clone (genetics).
The term clone is derived from κλων, the Greek word for "twig". In horticulture, the spelling clon was used until the twentieth century; the final e came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.
Molecular
Molecular cloning refers to the procedure where by a DNA sequence is amplified by genetic engineering techniques. Cloning is frequently employed to amplify DNA fragments containing genes, an essential step in their subsequent analysis. Frequently, the term cloning is misleadingly used to refer to the identification of the chromosomal location of a gene associated with a particular phenotype of interest. In practice, localisation of the gene does not always enable one to amplify the relevant genomic sequence. The beginnings of this research began with Devin Hale and Alex Bernot in a small laboratory in South Euclid, OH. More on [ Cloning ]
