     During the past few centuries, technology has reached a new level. With breakthroughs from the invention of electricity to the development of the Internet, these advances have made a huge impact on society. Every day brings the question of what will come next, and what technologies will further enhance the world. Science fiction novels and movies are essentially based on the wonder of future technologies. One of the biggest issues in the development of technology is cloning. The word clone is used in many different contexts in biological research but in its most simple and strict sense, it refers to a precise genetic copy of a molecule, cell, plant, animal, or human being.1

Incellular cloning copies are made of cells derived from the soma, or body, by growing these cells in culture in a laboratory.3 The cloned cells that are made are identical to the original cell. This method is also used for creation of medicines that molecular cloning creates. Since these methods do not involve germ cells, they are not beneficial in producing a baby.
     The objectives of blastomere separation and nuclear transplantation cloning, however, are to reproduce genetically identical animals. In blastomere separation, the developing embryo is split very soon after fertilization when it is composed of two to eight cells.4 These individual cells are called blastomeres. The blastomeres are now able to generate new separate organisms. The blastomere’s ability to produce new organisms makes it possible for scientists to split animal embryos into many cells that make genetically identical organisms. This is beneficial to breeding livestock. During the 1980s, cloning animals reached a new level called nuclear transplantation cloning. In nuclear transplantation cloning, the nucleus is removed from an egg and replaced with the
Antosh 3 diploid nucleus of a somatic cell.5 This type of cloning differs from sexual reproduction because in sexual reproduction, the egg and sperm combine. In nuclear transplantation cloning, a new organism is created by a single parent.
