The Nobel Stamps of 1989

The stamps were engraved by Martin Mörck after originals by Göran Österlund. Printed by recess/offset at the PFA. The FDC illustration is by Göran Österlund and the postmark is by Jan Magnusson.

 

The stamps portray Nobel Laureates in Physiology or Medicine:

The discoveries of eight geneticists are presented. Using fruit flies MORGAN showed how the genes are linked in the chromosomes. (1933)

WATSON and CRICK solved the riddle of the molecular structure of DNA with the aid of WILKINS' diffractogram. The DNA molecule contains the genetic material storing hereditary information. (1962)

ARBER, NATHANS and SMITH (1978) discovered the enzymes with which it is possible to cut a DNA molecule in predetermined places. If DNA molecules are cut from different animal species, the ends can be joined together to form hybrid DNA molecules. McCLINTOCK (1983) discovered how genes sometimes change places on the chromosomes, the so called "jumping genes. "
