Why the activity of a gene depends on its neighbors
... Which proteins might stabilize specific contacts? We begin with transcription factors because they provide the necessary specificity. Many factors (either acting alone, or complexed with others) are ‘bivalent’ in the sense that they (or the complex) can bind to two different segments of DNA to form ...

RNA polymerase finds the promoter region of a gene with help from transcription factor polypeptides which in turn are signaled by the cell to recognize particular genes. RNA polymerase binds to the DNA doub ...
