Ernst Haeckel
In 1865, Supported in Charles Darwin’s theory but didn’t believe in natural selection. Most famous for his work on radiolaria. Helped spread Charles Darwin’s theory around so that other scientists could learn, make theories, and experiment just like him. This is interesting to me because he believed in the inheritance of DNA but he dosn't believe in Darwin's natural selection theory which these facts are like cousins to each other, so close in roles of Gentic biology. -
Gregor Mendel's identifies inheritance
In 1865, Identifies inheritance factors in pea plants. Was the very beginning of the discovery of DNA, genetics, and biology but his theory was largely rejected at the time because scientists didn’t think for this information to be crucial. This event is interesting to me because even though the theory was largely rejected at the time it was one of the sole reasons why we are here in our advancement in DNA today. -
Thomas Hunt Morgan's discovery on location of genes
In 1910, Found out about genes and their location in chromosomes. Helped transform biology into an experimental science If he hadn't discovered this we would've been the dark of gene inheritance -
Erwin Chargaff's discovery on DNA structure
January, 1950, Erwin noticed the ratio of Adenine to Thymine were equal, as Cytosine to Guanine were also equal. This discovery became known as the Chargaff Ratios. This is event is significant to the discovery of DNA because it would play a crucial role in learning the structure of DNA. -
Rosalind Franklin's high X-ray diffraction photograph
In 1951, Produced a high quality X-Ray diffraction photograph to expose more aspect of repeating structure of DNA. This event helped scientists learn more about DNA, viruses, coal, and graphite. Her work was an important influence on Watkins & Crick’s hypothesis. This machiene helped DNA science become more testable along with many other things. -
Maurice Wilkins
In 1953, Proposed the double helix as the three-dimensional structure of the DNA molecule. Contributed to the scientific understanding of phosphorescence, isotope separation, optical microscopy and X-ray diffraction. -
James Watkins & Francis Crick
Discovered the structure of DNA .
Science discoveries about the molecular structure of nucleic acids and its information transfer in living material Helped DNA become more testable -
Alfred Hershey & Martha Chase
In 1953 these partners helped confirm the role of heredity in the DNA & that DNA itself was the carrier of information. Helped set the roadway for genetic DNA science. -
John Sulston
In 1998, Helped with the first sequencing of an animal’s genomes. Inspired the project to sequence the human genome. -
Oswald Avery's identification
In 1943 Oswald extended Griffith’s work by identifying DNA as the transforming factor. This discovery represents the birth of molecular biology.
