<p><font size="3"><strong>Genomics</strong> is the omics study of genes of individual organisms,&nbsp;populations, and species. <br /></font></p><p><font size="3">It is also a paradigm of performing biological science that deviates from&nbsp;investigating single genes, their functions, and roles. <br /></font></p><p><font size="3">The main reason of an independent biological discipline is that it deals with very large sets of genetic information to automatically analyze information using interaction and network concepts. Genomics inevitably employs high performance computing and bioinformatics technologies.</font><br /></p><p><span class="editsection"></span><span class="mw-headline"><font size="4"><br /></font></span></p><p><strong><span class="mw-headline"><font size="4">History of the field</font></span></strong></p><p><font size="3">Genomics was practically founded by Fred Sanger group in 1970s when they developed&nbsp;a gene sequencing technique and completed the first genomes; namely bacteriophage &Phi;-X174; (5,368 bp),&nbsp;the human mitochondrial genome, and lamda virus.</font></p><p><font size="3">In 1972, Walter Fiers and his team at the Laboratory of Molecular Biology of the University of Ghent (Ghent, Belgium) were the first to determine the sequence of a gene: the gene for Bacteriophage MS2 coat protein.<sup class="reference" id="_ref-0">[1]</sup> In 1976, the team determined the complete nucleotide-sequence of bacteriophage MS2-RNA.<sup class="reference" id="_ref-1">[2]</sup> The first DNA-based genome to be sequenced in its entirety was that of bacteriophage &Phi;-X174; (5,368 bp), sequenced by Frederick Sanger in 1977<sup class="reference" id="_ref-2">[3]</sup>. The first free-living organism to be sequenced was that of <em>Haemophilus influenzae</em> (1.8 Mb) in 1995, and since then genomes are being sequenced at a rapid pace. A rough draft of the human genome was completed by Sanger centre and the Human Genome Project in early 2001.</font></p><p><font size="3">As of September 2007, the complete sequence was known of about 1879 viruses <sup class="reference" id="_ref-3">[4]</sup>, 577 bacterial species and roughly 23 eukaryote organisms, of which about half are fungi. <sup class="reference" id="_ref-4">[5]</sup> Most of the bacteria whose genomes have been completely sequenced are problematic disease-causing agents, such as <em>Haemophilus influenzae</em>. Of the other sequenced species, most were chosen because they were well-studied model organisms or promised to become good models. Yeast (<em>Saccharomyces cerevisiae</em>) has long been an important model organism for the eukaryotic cell, while the fruit fly <em>Drosophila melanogaster</em> has been a very important tool (notably in early pre-molecular genetics). The worm <em>Caenorhabditis elegans</em> is an often used simple model for multicellular organisms. The zebrafish <em>Brachydanio rerio</em> is used for many developmental studies Define Genomics your own way after doing research on the molecular level and the flower <em>Arabidopsis thaliana</em> is a model organism for flowering plants. The Japanese pufferfish (<em>Takifugu rubripes</em>) and the spotted green pufferfish (<em>Tetraodon nigroviridis</em>) are interesting because of their small and compact what genomes, containing very little non-coding DNA compared to most species. <sup class="reference" id="_ref-5">[6]</sup> <sup class="reference" id="_ref-6">[7]</sup> The mammals dog (<em>Canis familiaris</em>), <sup class="reference" id="_ref-7">[8]</sup> brown rat (<em>Rattus norvegicus</em>), mouse (<em>Mus musculus</em>), and chimpanzee (<em>Pan troglodytes</em>) are all important model animals in medical research.</font></p><p><font size="3">&nbsp;</font></p><p><span class="editsection"></span><strong><span class="mw-headline"><font size="4">Bacteriophage Genomics</font></span></strong></p><p><font size="3">Bacteriophages have played and continue to play a key role in bacterial genetics and molecular biology. Historically, they were used to define gene structure and gene regulation. Also the first genome to be sequenced was a bacteriophage. However, bacteriophage research did not lead the genomics revolution, which is clearly dominated by bacterial genomics. Only very recently has the how we study of bacteriophage genomes become prominent, thereby enabling researchers to understand the mechanisms underlying phage evolution. Bacteriophage genome sequences can be obtained through direct sequencing of isolated bacteriophages, but can also be derived as part of microbial genomes. Analysis of bacterial genomes has shown that a substantial amount of microbial DNA consists of prophage sequences and prophage-like elements. A detailed database mining of these sequences offers insights into the role of prophages in shaping the bacterial genome.<sup class="reference" id="_ref-McGrath_0">[9]</sup></font></p>
