Cloning technique (third of 3 pictures). Light micrograph of a sheep egg being injected with an embryonic cell during sheep cloning. The egg (at centre) has had its DNA genetic material removed. At left a pipette holds the egg; at right a microneedle injects an embryonic sheep cell into it. Photos G285/017 & G285/018 show previous stages in the technique. The implanted egg is then stimulated to grow into a lamb by a spark of electricity,nourished in the womb of a surrogate sheep. In 1996,this research at the Roslin Institute in Edinburgh,Scotland,produced the world's first cloned (genetically identical) sheep | |
