The process of producing proteins is called as gene expression, and it is a tightly regulated process so that it can be modified depending upon the requirement of the cell. In this chapter we are discuss the concept of gene regulation in bacterial cells. Group of two or more genes in ...
Die Genexpression in Prokaryoten kann durch Operons gesteuert werden. Die DNA-Sequenzen bestehen aus regulatorischen Elementen und geclusterten, funktionell verwandten proteinkodierenden Genen. Operons verwenden eine bestimmte Promotorsequenz, um die Tra

Gene expression can be regulated at the stage of transcription, RNA processing (post- transcriptional changes), and translation. In prokaryotes, the on–off of transcription serves as the main regulatory control of the gene expression whereas, in eukaryotes, more complex regulatory mechanism of transc...
Prokaryotic Gene Regulation In prokaryotes, the main site for regulation of gene expression is transcription initiation. Within a transcription unit, the activity of RNA polymerase at the promoter is regulated by ‘accessory proteins’. These proteins affect the ability of RNA polymerase to recognize ...
