<p><strong>1) Define Genomics</strong> is the omics your own way after doing research on what genomes are and how we study of genes of individual organisms, populations, and species. It is also a paradigm of performing science that deviates from investigating single genes, their functions and roles. The main reason of an independent biological discipline is that it deals with very large set of genetic information to automatically analyze information using interaction and network concepts. Genomics inevitably employs computing and bioinformatics.</p>

The most important tools here are microarrays and bioinformatics. Study of the full set of proteins in a cell type or tissue, and the changes during various conditions, is called proteomics.?</p> <pul> <li>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 genomics = gene: the gene for Bacteriophage MS2 coat protein.+ omics<sup class="reference" id="_ref-0"/li>[1] </supli> In 1976, the team determined the complete nucleotide-sequence of bacteriophage MS2-RNA. <sup class="reference" id="_ref-1"ul>[2] </supli> The first gene = locus of DNA-based genome containing genetic information which is mostly related to be sequenced phenotype</li> <li>omics = field of study in its entirety was that of bacteriophage biology class &Phigt;-X174> (5proteomics ,metabolomics ,368 bp)lipidomics , sequenced by Frederick Sanger in 1977transcriptomics...<sup class="reference" id="_ref-2"/li>[3] </supul>.

Some new and exciting examples of progress in this field are the identification of genes for regulatory RNAs, insights into the evolutionary origin of photosynthesis, or estimation Epigenomics : set of the contribution of horizontal gene transfer to the genomes that have been analyzed.<sup class="reference" id="_ref-Herrero_0">[10]epigenetic modification</supli></pul>
