Working on pea plants, Gregor Mendel reports that the inheritance of certain traits follows a particular pattern, discovering the notion that heredity is transmitted in discrete units that will later be referred to as genes.
Frederick Miescher isolates DNA from white blood cells and calls it nuclein. He was the first to identify DNA as a distinct unit.
Walther Flemming produces the first illustration of a human chromosome.
Walter Sutton and Theodor Boveri independently observe that Mendel’s inheritance pattern corresponds to chromosome inheritance during meiosis, the cell division that produces reproductive cells, i.e. the sperm and egg cells.
Research conducted by William Bateson, Elizabeth Saunders and Archibald Garrod shows that alkaptonuria, also known as black bone disease, is inherited according to Mendelian rules.
The “Debate On Heredity And Disease” organized by the Royal Society of Medicine takes place in London.
is first formulated by Wilhelm Johannsen, who also defines the terms genotype and phenotype, referring respectively to the hereditary information and to the observed properties of an organism.
Working on the fruit fly Drosophila melanogaster, Thomas Hunt Morgan demonstrates that genes are carried by chromosomes and are the mechanical basis of heredity.
Archibald Garrod publishes his second book, “Inborn Factors in Disease” where he discusses the idea of inherited predisposition to a disease, setting the foundations for modern concepts of multifactorial inheritance.
JBS Haldane provides an estimate of the frequency at which mutations that cause haemophilia arise.
Ronald Fisher, among others, suggests the tracing of linked genetic markers to predict a disease.
Julia Bell and JBS Haldane demonstrate the linkage between genes for colour-blindness and haemophilia.
In their experiments using the red bread mold, Neurospora crassa, George Beadle and Edward Tatum’s show that genes act by regulating distinct chemical events. They propose that each gene directs the formation of one enzyme.
William Astbury obtains the first X-ray diffraction pattern of DNA, which reveals that DNA has a regular periodic structure. He suggests that nucleotide bases are stacked on top of each other.
Oswald Avery, Colin MacLeod, and Maclyn McCarty show that DNA, not proteins, can transform the properties of cells, thus clarifying the chemical nature of genes.
Carl Cori and Gerty Cori discover the Glycogen storage disease type 1 results form a deficiency in the enzyme glucose-6-phosphatase.
Based on the X-ray crystallography studies of DNA by Rosalind Franklin, Francis Crick and James Watson describe the double helix structure of DNA. They received the Nobel Prize for their work in 1962.
Joe Hin Tjio defines 46 as the exact number of chromosomes in human cells.
Arthur Kornberg and colleagues isolated DNA polymerase, an enzyme that catalyzes the template-directed synthesis of DNA that would later be used for DNA sequencing.
In the same year, three groups discover that anomalies in chromosome numbers lead to Down, Turner and Klinefelter syndromes (discovered by Jérôme Lejeune, Charles Ford and Patricia Jacobs and John Strong, respectively).
Robert Guthrie develops a method to test newborns for the metabolic defect, phenylketonuria (PKU).
Marshall Nirenberg and Heinrich Matthaei figure out the genetic code that allows nucleic acids with their 4-letter alphabet to determine the order of 20 kinds of amino acids in proteins.
Mark Steele and Roy Breg use cells obtained form amniotic fluid to perform fetal chromosome evaluation.
Scientists describe restriction nucleases, enzymes that recognize and cut specific short sequences of DNA. The resulting fragments can be used to analyze DNA, and these enzymes later became an important tool for mapping genomes.
Lore Zech, Torbjörn Caspersson and colleagues develop the use of quinacrine, a fluorescent dye that intercalates into DNA, to visualize dark and light bands on chromosomes. These bands form unique patterns for each chromosome that makes them discernable from one another.
Theodor Friedmann and Richard Roblin suggest the use of exogenous DNA to replace the defective DNA in patients suffering from genetic defects.
Two groups, Frederick Sanger and colleagues, and Alan Maxam and Walter Gilbert, both develop rapid DNA sequencing methods.
Scientists successfully add stably inherited genes to laboratory animals. The resulting transgenic animals provide a new way to test the functions of genes.
Scientists begin to submit DNA sequence data to a National Institutes of Health (NIH) database that is open to the public.
Murray and colleagues link the locus responsible for Duchenne muscular dystrophy to genetic markers on the short arm of the X chromosome.
A method for finding a gene without the knowledge of the protein it encodes is developed. The first human disease gene identified by positional cloning is responsible for chronic granulomatous disease (CGD), an inherited immunodeficiency.
Kary Mullis develops the PCR technique to amplify DNA, rapidly generating billions of copies of a specific sequence thus facilitating its study. Mullis was awarded the Nobel Prize in Chemistry in 1993 for his work on the PCR technique.
The first comprehensive genetic map is based on variations in DNA sequence that can be observed by digesting DNA with restriction enzymes.
The US Department of Energy and the National Institute of Health announce a plan for a 15-year project to sequence the human genome. This will eventually result in sequencing all 3.2 billion letters of the human genome.
A four-year-old girl with severe immunodeficiency became the first patient to undergo gene therapy in the United States. The effect of the therapy were temporary, but successful.
With a combination of fine genetic mapping and DNA sequencing, the gene responsible for Huntington’s disease is cloned, and mutations within it are identified.
‘Dolly the sheep’ is the first animal ever cloned in the Roslin Institute, Edinburgh.
The first finished, full-length sequence of a human chromosome is produced. Chromosome 22 was chosen to be first because it is relatively small and had a highly detailed map already available. Such a map is necessary for the clone by clone sequencing approach.
‘Draft sequence’ of human genome announced jointly by International Human Genome Consortium and by Celera. By the end of Spring 2000, HGP researchers sequence 90% of the human genome with 4-fold redundancy.
Gene therapy trial for the treatment of severe combined immune deficiency (SCID). But 2 out of the 10 boys that entered the trial in Paris developed leukemia-like disorders.
The finished sequence covers 99% of the human genome and is 99.99% accurate.
The world's first gene therapy is approved in China for the treatment of head and neck cancer.

A GWA study proves efficient in finding a common variant in complement factor H gene (CFH) to be strongly associated with age-related macular degeneration, the major cause of blindness in the elderly.
Since 2005, thousands of GWAS studies have provided robust genetic associations to common multifactorial disorders.
