  • The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)
  • However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
  • Thus, the clone would be genetically identical to the nucleus donor only if the egg came from the same donor or from her maternal line. (who.int)
  • When the nucleus of a stem cell has been the technique of cloning. (who.int)
  • The basic techniques of of the implanted nucleus, when it fully cloning have been known for some time, and develops. (who.int)
  • As part of its charge, the committee was asked to prepare a subreport evaluating methods for detecting potential unintended compositional changes across the spectrum of messenger ribonucleic acid (mRNA), proteins, metabolites and nutrients that may occur in food derived from cloned animals that have not been genetically modified via genetic engineering methods. (nationalacademies.org)
  • It defines the term "cloning of a human being" inaccurately. (cbc-network.org)
  • If it is to be brought to birth, the process is usually called "reproductive cloning. (cbc-network.org)
  • The process has been difficult to do with human cells. (usf.edu)
  • They repeated the process - this time starting with the genetic material extracted from the skin cells of a much older man. (usf.edu)
  • What we show for the first time is that you can actually take skin cells, from a middle-aged 35-year-old male, but also from an elderly, 75-year-old male" and use the DNA from those cells in this cloning process, Lanza says. (usf.edu)
  • When the cloning process is used in this way, to produce a living duplicate of an existing animal, it is commonly called reproductive cloning. (eurostemcell.org)
  • Cloning is an important process in Recombinant DNA technology. (wisdomanswer.com)
  • This is part of the natural aging process that seems to happen in all cell types. (wisdomanswer.com)
  • Since the term "born" has been used as an essential part of the definition of " reproductive cloning " used by Weissman, the National Academy of Sciences, etc., then it is critical to use the accurate term with the proper meaning. (lifeissues.net)
  • your supposed cloning ban actually authorizes human cloning, implantation, and gestation through the ninth month. (cbc-network.org)
  • The term "clone", from the Greek word for twig, denotes a group of identical entities. (who.int)
  • Beyond this scientific interest, the commercial concern in animal cloning focuses on replicating large numbers of genetically identical animals, especially those derived from a progenitor that has been modified genetically. (who.int)
  • 1. Cloning is an umbrella term traditionally used to describe different processes for duplicating biological material. (who.int)
  • He'd like to see a library of cells created with those carefully chosen genes. (usf.edu)
  • Dr. Irving, whose Ph.D. included a doctoral concentration in secular bioethics at the world's foremost bioethics institute, noted that the bill was poorly prepared using faulty science and lacking basic definitions necessary to have the law actually ban cloning as it claims it does. (lifesitenews.com)
  • They injected it into 77 human egg cells, and from all those attempts, managed to create two viable cells that contained DNA from one or the other man. (usf.edu)
  • More than 90% of cloning attempts fail to produce viable offspring. (wikiquote.org)
  • In this fashion, mice or other laboratory animals that exhibit particular traits can be created for specialized studies, or herds of farm animals (such as goats, sheep or cows) can be created that produce pharmaceutically useful proteins in their milk. (who.int)
  • Though fraught with problems, reproductive cloning at least strives to reproduce a human being and, in principle, preserves the value of human life. (reasons.org)
  • Nonetheless, he promises: "We will ensure that our government never opens the door to the use of cloning for human reproduction. (theinterim.com)
  • The developments utilizing adult stem cells, however, have been truly amazing with medical treatments (not mere potential or grand promises) already helping thousands of people. (blogspot.com)
