Happy National DNA Day! April 25 marks the 60th anniversary of scientists’ discovery of the double helix. It’s also the 15th anniversary of the completion of the Human Genome Project, which set out to sequence the more than 3 billion letters in our genetic code.
Biologist James Watson and physicist Francis Crick realized our DNA molecules form a three-dimensional double helix in 1953. But DNA research dates back to the late 1860s, according to Nature Education.
