Erwin Chargaff analyzes the base composition of DNA in cells.
Alfred Hershey and Martha Chase confirm that the genetic material of viruses is DNA, not protein.
Rosalind Franklin records a critical X - ray diffraction pattern, demonstrating that DNA is in the form of a helix. Maurice Wilkins studied DNA by X-ray crystallographic techniques with Franklin.
