Christiane Nüsslein-Volhard

Christiane Nüsslein-Volhard (Born the October 20th 1942) is a genetician specialist in the development which accepted with Eric F. Wieschaus and Edward B. Lewis the Nobel Prize of physiology or medicine in 1995 for their work on the genetic control of the early development of the Embryon by using the fruit fly or Drosophila melanogaster .

In 1978 it joined Wieschaus as chief of the European Laboratoire of molecular biology and spent more than one year to study with Wieschaus the Chromosome S of 40.000 Drosophila melanogaster with the binocular microscope. They concluded that on 20.000 genes of Drosophila melanogaster 5.000 are important and 140 are essential.

The genes of segmentation of the insect are divided into three categories:

  • genes gap : antèro-posterior development.
  • genes even rule : segmentation.
  • genes polarity of segment : persons in charge of the repetition of the structure in each segment.

It received the Prix Gottfried Wilhelm Leibniz in 1986.
