20. 20 A Brief History of Genetics 1859 Charles Darwin published “The Origin of Species.” 1865 Genes are particular factors. [Gregor Mendel] 1869 Discovery of nucleic acid [Friedrich Miescher] 1903 Chromosomes are hereditary units. [Walter Sutton] 1910 Genes lie on chromosomes. [Thomas Hunt Morgan] 1913 Chromosomes are linear arrays of genes. [Alfred Sturtevant] 1931 Recombination occurs by crossing over. [Harriet Creighton and Barbara McClintock]

21. 21 A Brief History of Genetics (cont’d) 1944 DNA is the genetic material. [Oswald Avery, Colin McLeod and Maclyn McCarty] 1953 DNA is a double helix. [James Watson and Francis Crick] 1961-1967 Genetic code is triplet. [Marshall Nirenberg, Har Gobind Khorana, Sydney Brenner & Francis Crick] 1977 DNA was sequenced for the first time.

38. 38 Ten Steps to Success in Bioinformatics by Webb Miller 1.Become a biologist. 2.Value your number of citations above your number of publications. 3.Collaborate, and do it with great collaborators. 4.Do not expect a warm welcome from everyone. 5.Be a good collaborator. 6.Distribute and maintain software and/or run web servers that you personally continue to use.

39. 39 10 Steps to Success in Bioinformatics by Webb Miller 7.Alternate between working on specific datasets and writing general-purpose software. 8.Write some of your own software. 9.Don't give up. 10.Be excited about your work.
