This stamp from France,
year 2001, has a strange DNA molecule. |

1988 Israel stamp
honoring its genetic engineering industry. |

This 2004 stamp from USA
recommends an early genetic test for detection of the sickle cell
disease. It is a hereditary, genetic disease more common on people with
African and Mediterranean basin origin, since it offers some inmunity
to malaria in their countries of origin.

In this stamp dedicated
to Biology, a double helix can be seen on the background, hold by a
man. It was issued on the occasion of the 250th anniversary of the
Duchy of Liechtenstein
(1969).

France issued this stamp
honoring Jacques Monod (1910-1976), who, with François
Jacob and
André Lwoff, received the Medicine 1965 Nobel prize for "for
their discoveries concerning genetic control of enzyme and virus
synthesis". They discovered the coordinated genetic regulation of
bacterial operons. It shows the words "Molecular Biology". (1987)

Stamp dedicated to
Biotechnology, where genetoic ingeneering is mentioned with those thre
double helices, next to the stamp value. Israel, 2000.

Barbara McClintock
(1902-1992), american researcher who discovered transposable elements,
DNA fragments able to move around the genome. She received the Nobel
prize in 1983 (see previous page).
The graphic represent one of those elements, showing the word
"geneticist". USA 2005.

Erich Tschermak-Seysenegg
(1871-1962)
was an Austrian botanist who re-discovered the so-called "Mendel's
laws" in 1900. Mendel's work remained forgotten since its publication
in
1865. The same concluded Karl Correns and Hugo de Vries in 1900, who
recognized the previous experiments by Mendel. This issue cellebrate
his
centenary birth. Austria, 1971.

This stamp was issued
honoring the VI Meeting of the Federation of European Biochemistry
Societies (FEBS), which took place in Madrid in 1969, due to the
insistence of Alberto Sols. It shows a DNA molecule and a table with
the genetic code (without the amino acids), making this stamp unique.
Spain, 1969.

In this stamp apppear
several Nobel prizes on Medicine. The second from the left is Thomas H.
Morgan (see page 1), geneticist who
received the prize in 1933 "for his discoveries concerning the role
played by the chromosome in heredity". Drosophila, the fruit fly, subject
of his research, also appears on the center. Comoros
Island, 1977.

This set of stamps shows
the nitrogen bases (guanine, citosine, adenine and timine), buildng
blocks of DNA, pairing between hidrogen bonds. Macau, 2001. Macau was a
Portuguese colony till integration into China in 1999.

This stamp commemorates
the 50th anniversary of the DNA structure discovery. It shows a simple
molecule model and a more complex volume structure, with a automatic
pipeting device Gilson-like. Monaco, 2003.

Stamp
featuring TeleThon, Italian foundation for the study of muscular
distrophy and other genetic diseases. The DNA molecule shows the
interests of genetic therapy as treatment for this diseases, incurable
today. The molecule has a misleading left-hand twist, as other stamps
from Israel
and Canada. DNA is a
right-hand helix, as most of the screws and cork screws. Italy, 2002.

Michael Smith was awarded
with the 1993 Chemistry Nobel Prize "for his fundamental contributions
to the establishment of
oligonucleotide-based, site-directed mutagenesis and its development
for protein studies". He developed a technique used in thousands of
laboratories to study genetic processes. It features a DNA molecule
with letter, simbols of the DNA components. Canada 2004.

Belgium issued several
sets of stamps dedicated to the milenium ended in 2000. This stamps
cellebrate the genetics discoveries fo the millenium with DNA molecule
in a baton from a relay race. Belgium, 2001.
