Friedrich Miescher
He was the first to describe DNA extracted from a cell nuclei. This model shows where DNA was found. An interesting fact I found is that he is known for his incorrect hypothesis of DNA. -
Frederick Griffith
His research ended up helping him find a clue about how DNA functions. The models he worked with include mice and bacteria. An interesting fact about Griffiths is he revealed the transforming principle. -
Barbara McClintock
Barbra McClintock made the discovery of jumping genes or she realized that genes can be mobile. She discovered that genes have the ability to change positions. This contributed to the discovery of DNA by expanding the knowledge on how much DNA is capable of. This model shows that genes have the ability reposition itself. An interesting fact about her is she never married. -
Oswald Avery, Maclyn McCarty & Colin McCleod
Avery, McCleod, McCary’s research plan was to identify the substance that caused transformation and basically tried to further prove Griffith’s experiment. Their contribution was to further prove that a DNA molecule is hereditary. The models that they worked with were proteins, lipids, carbs and DNA to prove that DNA is hereditary. An interesting fact about them is that 2 of them were born in Canada and the other one was born in the USA. -
Erwin Chargaff
He created the Chargaff’s rules about DNA. His contribution led to the reasoning that the basis of DNA depends on the species the DNA comes from. The model shows that DNA comes from a specific species. An interesting fact is that he lived until 2002. -
Linus Pauling
Pauling made it possible for geneticists to crack the code of DNA. He contributed to Watson and Cricks breakthrough of DNA. Pauling made a triple helix DNA model. An interesting fact about him is he lived to be 93 years old. -
Alfred Hershey & Martha Chase
Hershey and Chase worked together to find out that DNA satisfies the first property of a hereditary molecule. This research contributed to the knowledge of what DNA does. The models they worked with were bacteria, DNA, and radioactive isotopes. -
Rosalind Franklin & Maurice Wilkins
Franklin and Wilkins worked with the model of x-ray crystallization. They both discovered that DNA is passed down through generations. Their contribution to finding more about DNA was what it looked like, now that they had pictures. An interesting fact about Franklin is she originally went to study proteins, not DNA. An interesting fact about Wilkins is him and Franklin did not get along. -
James Watson & Frances Crick
Watson and Crick used the double helix model that they discovered for research. The contribution they made to the discovery of DNA is by using Franklin's research and realizing what DNA looked like. An interesting fact about Watson is he was very young when he studied DNA. An interesting fact about Crick is he was very creative. -
Matthew Meselson & Franklin Stahl
Matthew Meselson & Franklin Stahl concluded in their research that DNA can replicate itself. This contributed to the discovery of DNA by explaining how DNA was able to replicate itself. This model shows that DNA has the ability to replicate itself. An interesting fact about both was Meselson was born in Colorado and Stahl was born in Massachusetts. -
Frederick Sanger
The model that he used is used as the Sanger model. Sanger discovered that proteins were sequenced molecules and the DNA that make these proteins should have a sequence as well. His contribution to the discovery of DNA was proving that DNA has a sequence. An interesting fact is his father is also named Fredrick. -
Paul Berg
The model Berg used in research is known as a hybrid DNA. Berg’s research proved that DNA can be created from different types of organisms. This contributed to the discovery of DNA by further proving how DNA can be made. An interesting fact about him is he was born in June. -
Kary Mullis
Kary Mullis discovered that DNA can be copied in larger quantities. This contributes to the discovery of DNA by adding on how much DNA is capable of. This model shows what DNA looks like when being copied. An interesting fact is that Mullis passed away only 2 years ago. -
J. Craig Vente
J. Craig Venter did a lot of research about DNA and accomplished a few things. One of the things he did is he put together a team to transfect a cell with a synthetic chromosome. This contributes to the discovery of DNA by explaining how much DNA can uphold. This model shows the process of transfecting a cell. AN interesting fact is he discovered this one year after I was born.
