Miescher
Miescher is credited with the discovery of DNA.He did so by isolating phosphate rich chemicals from the nucleus of a white blood cell. These chemicals were named nucleic acids, and were later changed to deoxyribonucleic acid or DNA -
Chargaff
Edwin Chargaff is credited with the discovery of complementary base pairing. He did so through the creation of his rule that states that the amount pyrimidines is equal to the amount of purines in DNA. The only way that this is possible is of the purines pair with the pyrimidines, which partially proves complementary base pairing. -
Hershey and Chase
These scientists mainly tried to prove that DNA carries genetic material. To try and prove this , they conducted an experiment where bacteria were infected with bacteriophages. Once infected , the bacteria had only the DNA proteins from the bacteriophages, and not the regular proteins. -
Franklin
Franklin,(like Watson and Crick) took part in the discovery of DNA's double helix structure. Though she was not affiliated with them. She independently identified the basic proportions of DNA, and was published in the same book as Watson and Crick. -
Watson and Crick
The scientists James Watson, and Francis Crick are credited for the discovery of the chemical structure of DNA. Their discovery described DNA as a twisted ladder, but is known as a double-helix. The discovery of DNA is what prompted them to further research the properties of DNA, and the many experiments involving chemicals, they discovered the chemical structure of DNA. -
Meselson & Stahl
These scientists conducted an experiment to prove that DNA replication was semi conservative. in this experiment, they replace the nitrogenous bases in DNA with a heavier isotope of DNA to prove the semi conservative model
