Abstract
It came true at the beginning of 2001 that we can see all human genome sequences just by connecting to the Internet. It was the year that we used to dream, in the last century, the departure of starship “Discovery” bound for the Jupiter. Now, we have a powerful tool for learning how genomic DNA sequence varies among individuals, and what the role of such a single nucleotide polymorphism (SNP) is in the pathogenesis of diseases and responses to drugs. Comprehension of the genome will also accelerate the understanding of the transcriptome, the whole transcripts present in a cell, and the proteome, which controls the whole regulatory elements in a cell. In the near future, we can sub-classify the multifactorial diseases such as asthma into a set of diseases based upon the dysfunction of various molecules.
