Genetics originated in the work of Gregor Mendel (1822-1864) who named the units of inheritance he discovered genes. At the time, there were various conjectures about how they were stored in the cell, but that remained a mystery until the middle pf the 20th century when DNA was identified as the carrier of genetic information. DNA had been discovered in 1869, but its structure was unsure until X-ray diffraction crystallography by Rosalind Franklin under the direction of James Watson and Francis Crick in 1952-1953 revealed the double helix structure.
