Cell Animal Somatic Nucleus Nuclear Removed Adult Enucleated

The process of animal cloning by nuclear transfer involves removing the nucleus from a somatic cell of one animal and inserting it into an enucleated egg cell. After an electric shock to fuse and initiate division, the resulting embryo is transferred to a third animal's uterus to develop, creating a clone of the somatic cell donor.

El proceso de clonación animal por transferencia nuclear implica la extracción del núcleo de una célula somática de un animal y su inserción en un óvulo del que se ha extraído el núcleo. Tras una descarga eléctrica que induce la fusión y división celular, el embrión resultante se transfiere al útero de un tercer animal, produciendo un clon del donante de la célula somática.

Front Describe the process of cloning animals by nuclear transfer.
Back Somatic cell nuclear transfer:
  • Nucleus removed from somatic cell of adult animal
  • Nucleus removed from mature ovum harvested from different female animal of same species - enucleated
  • Nucleus from adult somatic cell is placed into enucleated ovum, given electric shock so it fuses and begins to divide
  • Embryo that develops is transferred into uterus of third animal where it develops 
  • New animal is a clone of the animal from which the original somatic cell is derived, mitochondrial DNA will come from egg cell
