-
Gregor Mendel
He did an experiment using peas that led to the discovery of genetics and how certain traits can be dominant. -
Friedrich Miescher
He discovered a substance containing both phosphorus and nitrogen in the nuclei of white blood cells found in pus. -
Thomas Hunt Morgan
He discovered a linear arrangement of the genes in chromosomes. -
Frederick Griffith
He experimented with mice and realized that one virus may have passed on the viral gene. He figured that this was caused by the passing of inheritance. -
Erwin Chargaff
He noticed a pattern in four different bases. He took samples of DNA of different cells and found that the amount of adenine was almost equal to the amount of thymine, and that the amount of guanine was almost equal to the amount of cytosine. -
Oswald Avery
He found the inheritance molecule, which was DNA, after continuing with Griffith’s experiment. -
Hershey and Chase
The results that Hershey and Chase obtained indicated that the viral DNA, not the protein, is its genetic code material. -
Rosalind Franklin
She tried to crystalize a DNA molecule to run an X-ray pattern. They discovered that the DNA had an X helix shape. -
Maurice Wilkins
He worked with Rosalind to crystalize a DNA molecule to run an X-ray pattern. They discovered that the DNA had an X Helix shape. -
James Watson & Francis Crick
These two found out the structure and appearance of DNA. -
Frederick Sanger
He figured out the determination of the structure of insulin and other proteins. -
John Sulston
He realized that certain cells in the lineage always died at a certain time by what seemed to be a programmed cell death.
