Cloning is the process of creating 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 encompases situations, whereby organisms reproduce asexually, but in common parlance refers to intentionally created copies of organisms



Cloning a cell means to derive a (clonal) 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 higher organisms, cell cloning is an arduous task as these cells will not readily grow in standard media.

A valuable tissue culture technique used to clone distinct lineages of cell lines involves the use of cloning rings (cylinders). 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.

I'm not sure what you mean, but I think you mean cloning. If so, here goes. Cloning is the process of creating 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 encompasses situations, whereby organisms reproduce asexually, but in common parlance refers to intentionally created copies of organisms.

In English that means replicating (copying) an organism using the DNA of the organism. There are also different types of cloning.
