Scientist using a technique called microinjection to introduce foreign or increased amounts of DNA into the genetic make-up of a cell. The work is done through a light microscope and visualised on a VDU screen as seen here. The circular cell is stablized by a suction tube (right) while the probe on the left introduces the genetic material. The dark area at the centre of the cell is the nucleus. Magnification: x150 at 35mm size (approx.).
