I. Introduction
The control of the gene expression has been a major issue in biology. One basic way that gene expression can be controlled by regulating transcription. In prokaryotes, our basic understanding of how transcriptional control of gene expression began with Francois Jacob and Jacques Monod’s 1960 model of the Lactose operon in which a regulator protein controls transcription by binding to a target region called the operator.

1. The gene expression
The genetic expression is the process of synthesizing proteins using genes, which is consisting the DNA. The protein is produced by the gene expression is essential to constitute living things and plays an indispensable role in survival. It can also hand over and preserve the genetic traits of living organisms in the next generation. The synthesis of proteins progresses in the following sequence: The RNA is made up from the DNA from coded genes. After the DNA transcribes the RNA, the RNA translates the protein
