He was the first to isolate DNA.
he showed how different diseases can transform or change.
They created and analyzed mutants of neurospora to show how genes directed to the synthesis of enzymes that control metabolic processes.
They thought DNA created a transformation in cells.
He developed the Chargoff Rule which states that the number of purines in DNA is equal to the amount of pyrimidines. G+A=T+C
She used x-ray diffraction to determine the structure of DNA.
Watson and Crick discovered that DNA was a double helix shape. They won the Nobel prize for their work in physiology.
He discovered how DNA is directed to the expression of proteins, and what role RNA had in these processes.
He discovered the structure of molecular nucleic acids.
