partial diploids with two copies of the lac-operon. When the copies created heterozyous cells (I + , I - ) normal regulation was observed. This indicated that the I gene codes for something that can move and interact with the operators of both copies of the lac-operon present in these...
The lac operon genes are transcribed and then translated into proteins necessary for transport and digestion of lactose. The operon is activated in the presence of lactose after glucose, the preferred carbon source, has been expended.;In this thesis, we introduce a biophysical model using the ...
In the absence of lactose, thelacrepressor is bound to the operator region of thelacoperon, physically preventing RNA polymerase from transcribing the structural genes. However, when lactose is present, the lactose inside the cell is converted to allolactose. Allolactose serves as aninducermolecule,...
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
