WHEN John Gurdon was 15, he ranked last out of the 250 boys in his grade at biology. He also came in last for every other science subject. His teacher wrote in a   16  : “I believe he has ideas about becoming a   17  ; on his present showing this is quite foolish.”

Luckily, the teacher’s words didn’t   18   Gurdon’s love for science. He kept working hard. He went to lab earlier and left   19   than anyone else.

On Oct 8, 2012, 64 years later, the British professor   20   the Nobel Prize for Physiology or Medicine. Japanese scientist Shinya Yamanaka had contributed to the research and therefore   21   the award.

Gurdon got the honor   22   his research into cells and cloning. When he was studying at Oxford, he did some   23   on cells. He took a cell from an adult frog, moved its   24  , and put them into an egg cell. The egg cell then   25   into a clone of the adult frog. His research   26   for the first time that every cell in the body contains the same genes.

At that time, many people   27   accept Gurdon’s idea. But later it helped to   28   Dolly the sheep in 1996, the first cloned mammal in history. It also led to important findings in the   29   use of cells. For example,   30   from someone’s skin can turn into any type of tissue in the body. This is good news for those   31   who have diseased or damaged tissue.

Gurdon always remembers the   32   he had when he was 15. He even put the report on his desk as a daily   33   to himself.

“When you have   34  , like an experiment doesn’t work, it’s nice to remind yourself that perhaps you are not so good at your job and the teacher may be   35  ,” he said.

However, the facts suggest Gurdon is pretty good indeed.
