Cloning

There are currently three types of cloning:

  • reproductive cloning
  • DNA cloning
  • therapeutic cloning

The type that most people think of when they hear the word 'cloning' is reproductive cloning. This involves constructing an egg using genetic material from another source. The egg then develops into an embryo, before being planted in a female host's uterus to continue to develop.

DNA cloning is a simpler method, whereby DNA is extracted from a host then replicated using plasmids. Even individual genes can be cloned in this manner.

Last, there is therapeutic cloning. This type of cloning is similar to reproductive cloning, however, stem cells are extracted from the embryo and used to treat the host. This type of cloning has many medical benefits for treating all sorts of diseases, but is highly controversial because of the destruction of the embryo following stem cell extraction.
