cloning

=Cloning= Back to Applications of genetics


 * Cloning** is the process of making an identical copy of something. In biology, it collectively refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. The term also covers when organisms such as bacteria, insects or plants reproduce asexually. For more info go to wikipedia

Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!You might not believe it, but there are human clones among us right now. They weren't made in a lab, though: they're identical twins, created naturally.

=Cellular Cloning = A useful tissue culture technique used to clone distinct lineages of cell lines involves the use of cloning rings (cylinders)[1]. According to this technique, a single-cell suspension of cells which have been exposed to a mutagenic agent or drug used to drive selection is plated at high dilution to create isolated colonies; each arising from a single and potentially clonally distinct cell. At an early growth stage when colonies consist of only a few of cells, sterile polystyrene rings (cloning rings), which have been dipped in grease are placed over an individual colony and a small amount of trypsin is added. Cloned cells are collected from inside the ring and transferred to a new vessel for further growth.
 * Cloning a cell** means to derive a population of cells from a single cell. In the case of unicellular organisms such as bacteria and yeast, this process is remarkably simple and essentially only requires the inoculation of the appropriate medium. However, in the case of cell cultures from multi-cellular organisms, cell cloning is an arduous task as these cells will not readily grow in standard media.

By cloning you can help a great deal; instead of having one of a good thing you would have 2 or more. however, you could clone something with good intentions, but have it backfire e.g accidentally clone a pathogen, etc.
