Cloning technique (second of 3 pictures). Light micrograph of a microneedle sucking up an embryonic sheep cell during cloning of sheep. The cell is then injected into a sheep egg that has been emptied of its DNA genetic material (see photos G285/017 & G285/019). The implanted egg is stimulated to grow into a lamb by a spark of electricity, nourished in the womb of a surrogate sheep. Each of these embryonic cells are identical and each can create an identical sheep. In 1996, this research at the Roslin Institute, Edinburgh, Scotland, produced the world's first cloned sheep. Cloned farm animals may provide benefits to agriculture and biotechnology.
