The text “The Mice That Roar” is an article dealing with the subject, cloning of mice. We read about a group of biologists from the University of Hawaii, who have done what most, scientist did not think was possible. Biologists Ryuzo Yanagimachi and his student Wakayama have succeeded in cloning adult mice, actually 50 clones have been manufactured. This is by itself great news, but it is also confirmation that the cloning of the sheep Dolly was a genuine.
The scientist use a method named the Honolulu technique. It works by extracting genetic material from a mouse’s socalled cumulus cell. This material is then injected into another mouse’s egg without DNA. This mouse gets a bath in chemicals, activating the production machinery. Then the embryo is transplanted into a mouse, where it grows into a cloned mouse.
Scientists agree this is a big step forward, in solving medical problems and the need of organ donors. It is a step in the development of xenoplantations, which mean using animal organs in humans. Also the technique can be evolved, so that doctors can correct genetic problems in human DNA.
As an ending of the article, it describes how scientists have proved that the cloning of the sheep Dolly was real.
