Dna, The Double-Helix, Genes & Genetics

A 200 Shekel banknotes issued by Israel in 1994 show Menorah, Jewish symbol, made of DNA double helix. The banknote commemorates Zalman Shazar, the first minister of education of Israel who initiated the free compulsory education law in Israel:

Gibraltar 2020, on the 100th anniversary of the birth of Rosalind Franklin.

Rosalind Franklin was the unsung hero of the DNA story. It was her X-ray crystallographic photograph 51 that was surreptitiously shown to James Watson by Maurice Wilkins that led Watson to understand the helical nature of the DNA molecule. Watson later gave credit to Franklin, but she went to her early grave (1958), not knowing the important role she played in one of the most important scientific discoveries of the 2oth century. There are two books that tell her story, Rosalind Franklin and DNA by Anne Sayre and Rosalind Franklin, the dark lady of DNA by Brenda Maddox.

Von Willebrand Disease (VWD), genetic hereditary blood-clotting disorder in humans due to a deficiency in the quality or quantity of von Willebrand factor (VWF), a protein involved in platelets cell functions, issued for use in Aland on May 5, 1994:

New stamp with DNA issued by Israel on February 11, 2025. It commemorates the 100th anniversary of the Technion, Haifa, Israel. The stamp shows molecule, atom and double helix DNA (upper right corner).

Biotechnology industry, issued by Canada on February 15, 1996 as one in a set of four stamps about "High technology in Canada". The stamp shows DNA double helix, chromosomes and Bacterial DNA plasmid used for genetic engineering.

Issued in a booklet contains two copies of the set. The cover (right) shows the Bacterial DNA plasmid (bottom right of the cover).

Inside the cover, descriptions of the different technologies. The bottom is about biotechnology and shows farm of genetic engineered plants.

Nikolai Ivanovich Vavilov (1887 – 1943) was a Soviet agronomist, botanist and geneticist who identified the centers of origin of cultivated plants. He devoted his life to the study and improvement of wheat, maize and other cereal crops that sustain the global population.

Vavilov's work was criticized by Trofim Lysenko, whose anti-Mendelian concepts of plant biology had won favor with Joseph Stalin. As a result, Vavilov was arrested and subsequently sentenced to death in July 1941. Although his sentence was commuted to twenty years' imprisonment, he died in prison in 1943. In 1955, his death sentence was retroactively pardoned under Nikita Khrushchev. By the late 1950s, his reputation was publicly rehabilitated, and he began to be hailed as a hero of Soviet science.

DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method that is used to determine the order of the four bases: AGCT. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery.

The first major sequencing methods were developed in the 1970s by Frederick Sanger and Allan Maxam & Walter Gilbert. Sanger sequencing, based on the chain termination method using dideoxynucleotides, became the dominant technique due to its efficiency and accuracy. Maxam-Gilbert sequencing, which relied on chemical cleavage of DNA at specific bases, was less commonly used due to its complexity and use of hazardous chemicals. Today, next-generation sequencing (NGS) has largely replaced these methods for high-throughput applications.

This stamp, issued by Australia on July 8, 2003, was already posted in page 1 of this thread but I found it with tab shows DNA sequencing analysis using Sanger method.

Malaria Virus? well, malaria is an infectious disease caused by unicellular parasite Plasmodium, not by a virus. This is what happen when you give a foreign agent permission to design and issue your stamps!

Any way, this "newly discovered" virus has DNA double helix. Same design of the DNA appears on the upper right corner of the SS.

The 70th anniversary of Bar Ilan University in Israel, issued by Israel on May 13, 2025. The stamp shows many symbols of education, science and technology including DNA double helix.
