Have you ever wished you could have a clone of yourself to do homework while you sleep or go out with your friends? Imagine if you could really do that. Where would you start? Cloning is a type of genetic engineering; this is the creation of an organism that is an exact genetic copy of another. This in simpler term means that every single bit of DNA is the same between the two. There are three species that can be cloned, which are: human, animal and plant. When the media report on cloning, they are usually talking about the two types of human cloning: reproductive and therapeutic cloning. The first type, reproductive cloning is the creation of many copies of an individual sharing the same set of genes. This process involves removing one or more cells from an embryo and encouraging the cells to develop into a separate embryo. This procedure has not yet been successfully carried out on human embryos but has been carried out on animals. Types of cloning : In biology, cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. The term also refers to the production of multiple copies of a product such as digital media or software. Cell cloning (the basis of cloning) : 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. There would be very little impact on the environment. We lack the technology to clone organisms as fast as mother nature can produce...
