Discovered DNA as a molecule, a novel molecule, Not only that, but he also discovered nucleic acids by isolating nuclien which was named from nuclei, human pus cells).

Discovered the shape/structure of DNA helix, but never finalized it made any conclusions. She used x-rays and the shadows from it to find out the shape was a helix. The image was called photos. To add on, her first discovery was the density of DNA.

discovered the shape of DNA as the twisted structure based off of other scientists prior work by using X-rays/Rosaland Franlin). They didn't only use Frankins research, but also used chargaff's and Wilkins combined to make a 3D model.

Found that DNA was hereditary material. Found that neither RNA nor RNA had the instructions needed for transformation. He removed organic compounds from S strain and then tested to see if what was left would cause transformation, but it didn’t so the material was not hereditary information.

His discovery was finding the ratios between A = T and C = G. He found out that Adenine is equal to Thymine and Cytosine is equal to Guanine.

Found that DNA is genetic information. They had tested a virus that infects bacteria. SHowed that the DNA of a virus needed bacteria to infect it.

Found that DNA was in a double helix structure. That DNA is paired with another base, and the bases fit from one strand to the other and are connected by a hydrogen bond.

Used two strains of bacteria, R and S. He injected mice with a heat-killed S bacteria and it did not give the mice disease. When the R and S bacteria were combined the mouse died and when a blood sample was taken it contained living S bacteria. He found that the R bacteria transformed from the S bacteria into a virus.
