Thomas Hunt Morgan
In his famous Fly Room at Columbia University Morgan was able to demonstrate that genes are carried on chromosomes and are the mechanical basis of heredity. -
Alfred Sturtevant
was an American geneticist. Sturtevant constructed the first genetic map of a chromosome in 1913. -
Fredrick Griffith
was a British medical officer and geneticist. In 1928, in what is today known as Griffith's experiment, he discovered what he called a transforming principle, which led to the direct discovery of how DNA works and the beginning of Molecular Genetics -
Jean Brachet
In 1933 Brachet was able to show that DNA was found in chromosomes and that RNA was present in the cytoplasm of all cells -
Fredrick Sanger
Sanger's first triumph was to determine the complete amino acid sequence of the two polypeptide chains of insulin in 1955. -
Tjio&Levan
was a cytogeneticist who is renowned because he was the first person to recognize the normal number of human chromosomes. -
Meselson-stahl
experiment by Matthew Meselson and Franklin Stahl in 1958 which supported the hypothesis that DNA replication was semiconservative. -
Beadle & tatum
Beadle and Tatum's fairly simple experiment was a keystone in the development of molecular biology. In its basic form, the concept that genes produce enzymes -
Walter fiers
At the California Institute of Technology Walter Fiers was exposed to Molecular Biology, which was then just developing, studying viral DNA. He demonstrated the physical, covalently closed circularity of Bacteriophage PhiX-174 DNA -
Yeast genome
Yeast genome is sequenced -
Howard Temin
was a U.S. geneticist. Along with Renato Dulbecco and David Baltimore he discovered reverse transcriptase in the 1970s at the University of Wisconsin–Madison, for which he shared the 1975 Nobel Prize in Physiology or Medicine. -
Fredrick sanger
He then turned to DNA and, by 1975, had developed the “dideoxy” method for sequencing DNA molecules, also known as the Sanger method. Two years later Sanger used his technique to successfully sequence the genome of the Phage Φ-X174; the first fully sequenced DNA-based genome. -
C. elegans genome
C. elegans (translucent worm) genome sequenced -
Drosophila genome
Drosophila (fruit fly) genome sequenced -
Arabidopsis genome
arabidopsis genome is sequenced -
mouse genome
mouse genome sequenced -
Human Genome Project
The human genome fully sequenced in 2003 -
brown rat genome
brown rat genome sequenced -
Chimp Genome
chimp genome presented to Nature program -
Dog genome
