What is "clone"

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.

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.

3. something virtually identical to another object.

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.

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.

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.

1903, in botany, from Greek klon "a twig, spray," related to klados "sprout, young branch, offshoot of a plant," possibly from PIE root *kel- (1) "to strike, cut" (see holt). Figurative use by 1978.

1959, from clone (n.). Related: Cloned; cloning. Extension to genetic duplication of animals and human beings is from 1970.

n. 1 A living organism (originally a plant) produced asexually from a single ancestor, to which it is genetically identical. 2 A copy or imitation of something already existing, especially when designed to simulate it. 3 A group of identical cells derived from a single cell. vb. To create a clone.

1. n. a person who is almost identical to another [syn: ringer, dead ringer]

2. a group of genetically identical cells or organisms derived from a single cell or individual by some kind of asexual reproduction [syn: clon]

3. an unauthorized copy or imitation [syn: knockoff]

4. v. make multiple identical copies of; "people can clone a sheep nowadays"

Clone may refer to:

In computing, a clone is a hardware or software system that is designed to function in the same way as another system. A specific subset of clones are Remakes (or Remades), which are revivals of old, obsolete, or discontinued products.

Clone is the first studio album from Leo Kottke and Mike Gordon. It was released on October 8, 2002, and features the duo performing acoustic originals and cover songs on a variety of instruments.

A '''database clone ''' is a complete and separate copy of a database system that includes the business data , the DBMS software and any other application tiers that make up the environment. Cloning is a different kind of operation to replication and backups in that the cloned environment is both fully functional and separate in its own right. Additionally the cloned environment may be modified at its inception due to configuration changes or data subsetting.

The cloning refers to the replication of the server in order to have a backup, to upgrade the environment.

clone is a method in the Java programming language for object duplication. In Java, objects are manipulated through reference variables, and there is no operator for copying an object—the assignment operator duplicates the reference, not the object. The clone method provides this missing functionality.

The process of immunological B-cell maturation involves transformation from an undifferentiated B cell to one that secretes antibodies with particular specificity. This differentiation and activation of the B cell occurs most rapidly after exposure to antigen by antigen-presenting cells in the reticuloendothelial system, and under modulation by T cells, and is closely intertwined with affinity maturation. B cells that respond most avidly to antigen are preferentially allowed to proliferate and mature, a process known as clonal selection.

In lymphocytic neoplastic diseases such as multiple myeloma and lymphoma, but also other illnesses, there can be a massive expansion of a single B-cell clone, detectable by measuring the excessively-produced antibodies, measured in a serum protein electrophoresis test or peripheral blood flow cytometry. Such an expansion is said to be "monoclonal", and monoclonal antibodies produced by such a group of B cells can cause illnesses such as amyloidosis and lupus, or can be indicative of an underlying malignancy. The concept of clonality is closely associated with malignancy, for example in diagnosing lymphomatoid skin lesions. The expansion of a particular clone of immune B cells is usually interpreted by clinicians as evidence of unrestricted cell growth, the hallmark of cancer.

Clone is the fourth studio album by British progressive metal band Threshold, released in 1998. This album is the first to feature longtime singer Andrew "Mac" McDermott and the final album to feature drummer Mark Heaney. In October 2012 Nuclear Blast released a "Definitive Edition", including three bonus tracks.

The album also comes closer than any other by the band to presenting a loose storyline through its songs, describing how the genetic manipulation of humans leads to the development of telepathy, and how these enhanced humans leave the earth to colonize other planets, eventually returning to Earth centuries later.

UK Planet Rock (radio station) DJ Darren Redick features on the introduction to the song 'Goodbye Mother Earth'.

In universal algebra, a clone is a set C of finitary operations on a set A such that

• C contains all the projections , defined by ,
• C is closed under (finitary multiple) composition (or "superposition"): if f, g, …, g are members of C such that f is m-ary, and g is n-ary for every j, then the n-ary operation is in C.

Given an algebra in a signature σ, the set of operations on its carrier definable by a σ- term (the term functions) is a clone. Conversely, every clone can be realized as the clone of term functions in a suitable algebra.

If A and B are algebras with the same carrier such that every basic function of A is a term function in B and vice versa, then A and B have the same clone. For this reason, modern universal algebra often treats clones as a representation of algebras which abstracts from their signature.

There is only one clone on the one-element set. The lattice of clones on a two-element set is countable, and has been completely described by Emil Post (see Post's lattice). Clones on larger sets do not admit a simple classification; there are continuum clones on a finite set of size at least three, and 2 clones on an infinite set of cardinality κ.

A clone is a group of identical cells that share a common ancestry, meaning they are derived from the same cell.

Clonality implies the state of a cell or a substance being derived from one source or the other. Thus there are terms like polyclonal—derived from many clones; oligoclonal—derived from a few clones; and monoclonal—derived from one clone. These terms are most commonly used in context of antibodies or immunocytes.

Clone is a 2008 BBC Three comedy series starring Jonathan Pryce and Mark Gatiss, centred on the creation and education of the world's first human clone. Its first series of six 30-minute episodes premiered on 17 November 2008.
