The Discovery of DNA- Doyle, Liam

Friedrich Miescher

1869

Isolated "Nuclein", DNA associated proteins.
First to distinct DNA as a molecule.
"As a boy he was shy but intelligent", I thought this was interesting because I am very similar. He achieved greatness despite his shyness.
This photo represents the original discovery of DNA, and the process by which it came.

Frederick Griffith

1928

Bacteria can transform & change function.
(Mouse Experiment)
He was born in Hale, England. This is a place I have always wanted to visit.
This photo models the experiment carried out by Mr.Griffith.

Barbara McClintock

1940

Genes are responsible for turning physical characteristics on & off.
She attended Erasmus Hall High School, which is where one of my great Aunts graduated from!
This shows the process of recombining DNA.

Oswald Avery, Maclyn McCarty & Colin McCleod

1944

Found that DNA is the material of genes & chromosomes.
McCarty attended Stanford University, which is one of my top schools.
This shows how the experiment to determine that DNA contained genetic material.

Erwin Chargaff

1950

Found that A & C should be equal and that A & T should be equal, within DNA.
I thought it was interesting that he immigrated to the United States and became so successful during such a rough era (Nazi).
The picture models the rule determined as result of the experiment.

Rosalind Franklin & Maurice Wilkins

1952

Discovered 2 forms of DNA (A & B) and Photo 51.
Wilkins parents were vegetarians, similar to my mother.
This is photo 51, which helped determine the structure of DNA.

James Watson & Frances Crick

1953

Discovered the model for the double helix structure of DNA.
He was very interested in bird watching. My grandparents love bird watching!
This picture of the structure of DNA represents their discovery of DNA's structure; a double helix.

Matthew Meselson & Franklin Stahl

1958

Proves DNA is "semiconservative".
Stahl was born on a Tuesday, like me!
The picture shows the model of semi-conservative DNA, which is the reason for his fame in the realm of DNA.

Linus Pauling

1964

Discovered the spiral structure of proteins.
He dropped out of high school to attend Oregon State University. I dropped out of Stem to go to West.
This is the sketch of Linus Pauling after discovering the structure of proteins.

Alfred Hershey & Martha Chase

1969

Proved that Phage DNA is not a protein, but the genetic material.
She died of pneumonia, I've had pneumonia 3 times.
This shows the experiment to prove the Phage is a genetic material.

Paul Berg

1971

Discovered the ideas of recombinant DNA, gene splicing.
First to combined genes from different organisms.
He went to Penn State around the same time as my grandpa!
This follows the process that Mr. Berg took to gene splice.

Frederick Sanger

1977

Developed a method to determine the order of bases in a structure of DNA.
He was a religious man, as am I.
This is a representation of his experimenting, and shows the process of ordering bases.

Kary Mullis

1985

Production of copies of DNA.
(Polymerase chain reaction)
I thought it was interesting that he claims drugs such as LSD helped his studies.
The picture is a model of his Polymerase Chain Reaction.

J. Craig Venter

2001

First draft of the human genome
He was named one of "The World's 50 Most Influential Figures 2010", so cool!
This is the process of creating a human genome as followed by Mr. Venters
