Gregor Mendel
Recognized mathematical patterns of inheritance from one generation to the next. Created Mendel's Laws of Heredity. -
Period: to
Discovering the Role of DNA
-
Walter Sutton
Walter Sutton showed that each chromosome is different and that meiosis reduces chromosome numbers in the gametes. -
Erwin Chargaff
Chargaff Rules were created and used to help lead to the discovery of the double helix structure in DNA. -
Thomas Hunt Morgan
Thomas Hunt Morgan came up with proof for the chromosomal theory of heredity, genetic linkage, chromosomal crossing over, and nondisjunction -
Frederick Griffith
He discovered the “Transformation Principle” in pneumococcus bacteria. He suggested the bacteria are capable of transferring genetic information through a process known as Transformation. This discovery is now known as “Griffith's experiment" -
Oswald Avery
Him and his team were the first to prove that DNA, not protein, is the genetic molecule. In the paper he published, he showed that isolated DNA as the material of which genes and chromosomes are made. -
Alfred hershey and Matrha Chase
Hershey-Chase experiments helped confirm that DNA is a genetic material -
Rosalind Franklin
Rosalind Franklin Obtained high resolution photos of crystallized DNA. She used these photos to figure out the basic dimensions for a strand of DNA. -
James Watson & Francis Crick
They discovered that the shape of DNA was a Double Helix, or a twisted ladder. -
Craig Ventor and Francis Collins
Human Genome Project and Genome sequencing is discovered which helps discover diseases and diagnosis in the genes. Which can be treated. From diabetes to heart disease to alzheimer's disease -
Human Genome Project Complete
Announced that the project had completed a high quality sequence of essentially the entire human genome. The projected completed drafts that were published in 2001. In addition to human genomes, they also worked on other organisms, such as yeast and the fruit fly.
