wat is cloning?

Answer 1

it is a technology used to create real like things/parts of body.After creating the thing in laboratory the same is implanted in the human body.And most surprising is the fact that our body readily accepts the same.Such things are created bu taking cells from the body of a person for whom it is to be created.

Answer 2

Cloning is the process of creating an identical copy of an original organism or thing. A cloning in the biological sense, therefore, is a molecule, 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 is asexually reproduced by chance (as with identical twins), but in common parlance, a clone is an identical copy created intentionally.

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.

Answer 3

*Cloning: The process of making a clone, a genetically identical copy. Cloning can refer to the technique of producing a genetically identical copy of an organism by replacing the nucleus of an unfertilized ovum with the nucleus of a body cell from the organism.

*The first adult mammal cloned was Dolly the Sheep in 1997.

*Cloning is a method of reproduction used to copy a cell or an individual (producing a clone) from their DNA . Except when there are errors or mutations during copying, a clone is genetically identical to the original: it has the same DNA. In nature, certain non-sexual species, like bacteria, employ cloning for reproduction. In the laboratory, researchers are studying the cloning of sexual species.

Answer 4

Cloning -- Using specialized DNA technology to produce multiple, exact copies of a single gene or other segment of DNA to obtain enough material for further study. This process, used by researchers in the Human Genome Project, is referred to as cloning DNA. The resulting cloned (copied) collections of DNA molecules are called clone libraries. A second type of cloning exploits the natural process of cell division to make many copies of an entire cell. The genetic makeup of these cloned cells, called a cell line, is identical to the original cell. A third type of cloning produces complete, genetically identical animals such as the famous Scottish sheep, Dolly.

Answer 5

Cloning is a scientific process where exact copies of individuals can be created. Suppose let us take the example of endangered species like tigers. In cloning process the genome of tiger is collected through centrifugation techniques and they are stored in gene banks under cold conditions. Whenever there is a need, the genome is transferred to a mother tigress and the development of the embryo starts and then finally the baby tiger cub. This process can be done only in scientific laboratories which are fully ecquipped.
Cloning is done using genetic engineering and bio tech applications.

Answer 6

Cloning refers to asexual reproduction, reproduction without 'fertilisation'. A cloned individual (clone from the Greek Klon, 'twig', 'slip') may result from two different processes: (1) Embryo splitting: this sometimes gives rise to monozygotic twins but can also result in identical triplets or even quadruplets. 2 (2) Cell Nuclear Replacement (CNR) or Cell Nuclear Transfer (CNT). This was the procedure that produced Dolly. CNR involves two cells: a recipient, which is generally an egg (oocyte), and a donor cell. Early experiments mainly made use of embryonic cells, which were expected to behave similarly to the cells of a fertilised egg, in order to promote normal development after the nuclear replacement. In more recent experiments, the donor cells were taken from either fetal or adult tissues. The nucleus of the donor cell is introduced into the egg (either by cell fusion or by injection). With appropriate stimulation - electric pulses or exposure to chemicals - the egg is induced to develop. The embryo thus
created may be implanted in a viable womb, and then develops in the normal way to term, although the failure rate has so far been high.

It is clear then that cloning did not start with the birth of Dolly nor yet did artificially produced clones start with the birth of Dolly. The first type of cloning was, as we have noted, the creation, through sexual reproduction, of so-called identical (monozygotic) twins. These sorts of clones have always been with us and, confining ourselves to humans for the moment, humankind has a vast, and on the whole successful, experience with them.

So, the first type of deliberate cloning we must consider is 'embryo splitting' which results in monozygotic twins.
When identical twins occur in nature they result from the splitting of the early embryo in utero and the resulting twins have identical genomes. This process can be mimicked in the laboratory and in vitro embryos can be deliberately split creating matching siblings.

Answer 7

Cloning is to make an exact copy , with the use of DNA it is now possible to make another you!! In the UK they made a sheep called Dolly, this was done by useing DNA from one sheep and re-creating another. One day they WILL clone people, they know how to, but are held back by laws at the moment.

Answer 8

Cloning is creating a replica of something. It looks the same.
Might even have the same behaiour if living if kept in the same environment as the original.

Answer 9

cloning: the process of making genetically identical copies. Used to refer to making many copies of DNA, usually by replication of a recombinant plasmid in a bacterium. The term is also used to refer to making many genetically identical copies of an organism.

Answer 10

cloning is the method of creating an animal in an artificial way(not giving birth)they take cell's from the parents & create it.example:dolly(a sheep)
