In 10 days (25 Apr) we'll be celebrating National DNA Day. I somehow missed it for the past 10 years since 2003 when it was officially designated to commemorate the 50th anniversary of the discovery of the structure of DNA by a couple of obscure (at the time) British scientists, Watson and Crick, in 1953. It's worth taking a look at that groundbreaking paper which begins humbly:
"We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.)."
The article includes the now-iconic illustration of the double-helix ladder structure with the caption: "purely diagrammatic."
After a few paragraphs of technical descriptions and postulates comes the prophetic phrase:
"It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material."
They were awarded the Nobel Prize in 1962. Paper can be viewed here: DNA Paper
Celebrations aside, FamilyTreeDNA uses the event to offer discounts on DNA tests. If you work in genealogy but haven't tested for DNA you're spinning your wheels. It's like having a family tree in a manila folder instead of WikiTree. But they work together, WikiTree and DNA testing--it's a powerful combination.
