The genetic experiments Mendel did with pea plants took him eight years . During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type. ("Genome news network," )

Isolated the first crude preparation of DNA, he just didn’t know it. He named it nuclein.("Interactive dna," 2012)

Showed that Fred Griffith’s “transforming principle" was DNA. (“Interactive dna,” 2012)

Discover that they can deduce the atomic structure of crystals from their X-ray diffraction patterns. This scientiFic tool will be key in helping Watson and Crick determine DNA's structure. ("Interactive dna," 2012)
1928
% complete
discovers that genetic information can be transferred from heat-killed bacteria cells to live ones. This phenomenon, called transformation, provides the first evidence that the genetic material is a heat-stable chemical. ("Hhmi," 2003)

Rosalind Franklin produced the X-ray crystallography pictures of DNA which Watson and Crick used to determine the structure of double-stranded DNA.("Hhmi," 2003)

He found that the amount of DNA and its nitrogenous bases varies from one species to another. Also Chargaff found that the amount of adenine equals the amount of thymine, and the amount of guanine equals the amount of cytosine in DNA from every species.("Hhmi," 2003)
