-
He was the first researcher to isolate and identify nucleic acid
-
he reported what is now known as Griffith's Experiment, the first widely accepted demonstrations of bacterial transformation, whereby a bacterium distinctly changes its form and function
-
The invention of recombinant DNA technology—the way in which genetic material from one organism is artificially introduced into the genome of another organism and then replicated and expressed by that other organism.
-
helped launch the molecular biology research program
-
studied the genetics of Drosophila, or the fruit fly.
-
was an experimental demonstration, reported that DNA is the substance that causes bacteria transformation.
-
his contributations to basic research, involving nucleic acids.
-
The Hershey–Chase experiments were a series of experiments
-
they made crucial contributions to the discovery of DNA's structure
-
They received the Nobel Prize in physiology or medicine for their determination of the structure of deoxyribonucleic acid (DNA).
-
The Meselson–Stahl experiment was an experiment by Matthew Meselson and Franklin Stahl which supported the hypothesis that DNA replication was semiconservative.
-
through careful experimentation, he discovered two rules that help lead to discovery of the double helix, structure of DNA.
-
He won the Nobel Prize in Physiology or Medicine for his discovery of "the mechanisms in the biological synthesis of deoxyribonucleic acid (DNA)".
-
He won a Nobel Prize in Physiology or Medicine for "breaking the genetic code" and describing how it operates in protein synthesis
-
In recognition of his improvement of the polymerase chain reaction (PCR) technique.
