Suggestion Sort the tables by date instead of the relatively irrelevant Latin name alphabetical order. Image S cerevisiae under DIC microscopy.jpg right thumb 180px Saccharomyces cerevisiae was the first eukaryotic organism to have its complete genome sequence determined. This list of sequenced eukaryotic genomes contains all the eukaryote s known to have publicly available complete Cell nucleus nuclear and organelle genome sequence s that have been assembled, annotated and published draft genomes are not included, nor are organelle only sequences. DNA was first sequenced in 1977. The first free living organism to have its genome completely sequenced was the bacterium Haemophilus influenzae , in 1995. In 1996 Saccharomyces cerevisiae baker s yeast was the first eukaryote genome sequence to be released and in 1998 the first genome sequence for a multicellular eukaryote, Caenorhabditis elegans , was released. Expand list date February 2011 Protists Alveolata Alveolata are a group of protists which includes the Ciliophora , Apicomplexa and Dinoflagellata . Members of this group are of particular interest to science as the cause of serious human and livestock diseases. class wikitable sortable style border 1px solid aaa Organism Type Relevance Genome size Number of genes predicted Organization Year of completion Babesia bovis Apicomplexa n Cattle pathogen 8.2 Mb 3,671 2007 ref name Brayton cite journal author Brayton KA title Genome Sequence of Babesia bovis and Comparative Analysis of Apicomplexan Hemoprotozoa journal PLoS Pathogens volume 3 issue 10 pages 1401 13 year 2007 doi 10.1371 journal.ppat.0030148 pmid 17953480 pmc 2034396 author separator , author2 Lau AOT author3 Herndon DR display authors 3 last4 Hannick first4 Linda last5 Kappmeyer first5 Lowell S. last6 Berens first6 Shawn J. last7 Bidwell first7 Shelby L. last8 Brown first8 Wendy C. last9 Crabtree first9 Jonathan ref Cryptosporidium hominis br small Strain TU502 small Apicomplexa n Human pathogen 10.4 Mb ... more details
