Cloning cows, nuclear transfer. Light micrograph of an egg (female reproductive cell) from a cow (Bos taurus) being manipulated by a micropipette (right) and needle (left) during the nuclear transfer stage of the cloning process. At this stage the genetic material from another cell is transferred into an egg cell which has had its genetic material removed. The work is being carried out at the Bio Sidus biotechnology company, in Argentina, which successfully cloned a cow in 2002. The cloned cows are intended to be used to produce human growth hormone (hGH) in their milk. Magnification: x150 when printed at 10 centimetres wide.
