Important notes: Johann Meischer’s analysis of old bandages used in the Crimean War led to his discovery of what he called nuclein in 1869. Watson and Crick defined the structure of DNA in 1953, which gave researchers a blueprint. Gilbert and Sanger described how to sequence DNA in 1977, which allowed researchers to analyze small parts of the structure. Alex Jeffery found the uniquely human part of the DNA strand in 1985, which made unique comparisons possible.
