Today (25 April) is World DNA Day, honoring the first publication of the molecular structure of deoxyribonucleic aced, on this date in 1953. My tie shows an image from gel electrophoresis, the biochemical analytical tool that helps to identify the sequence of amino acids in the helix of DNA. My tie clip is made from part of a computer circuit board. I chose it mistakenly because my calendar included a reference to the patenting of the microchip (actually in February).
Note about World DNA Day: "The aim of World DNA Day-2025 (WDD-2025) is to follow up the commemoration of the 72th anniversary of the publication of DNA double-helix structure in Nature from April 25, 1953 by Dr. James Watson and Dr. Francis Crick. WDD-2025, which is held in conjunction with The 14th World Gene Convention, The 11th Annual Conference of AnalytiX, The 15th World Congress of Regenerative Medicine & Stem Cell, The 15th Anniversary of Protein & Peptide Conference, The 10th Symposium on Enzymes & Bio-catalysis and Inaugurate World Congress of Biomedical Information Technology.
This “Seven in one” congress will be held in April 23-25, 2025 in Nara, Japan."
