We are living in an unprecedented age of biological discovery and the application of biological knowledge.   Programmed DNA sequencing delivered, in the year of  2001 over the 2.6 billion base pairs of DNA series in the human genome the Human Genome Project and the genomes of several other organisms have either earlier been or are being sequenced too.  This vast and ever-raising, wealth of DNA sequence data is a main asset for genomics, the learning of an organism's genome.  One  of  the  main key  target  is  to  understand  the  functions  of  the  vast numbers of new genes predicted by genome sequencing and a field called as functional  genomics
