The specific DNA sequences to which the transcription factors bind are

1.	The specific DNA sequences to which the transcription factors bind are referred to as _____(a) replication elements(b) blocking factors(c) transcription factors(d) regulatory elementsI have been asked this question by my school teacher while I was bunking the class.The origin of the question is Promoter and Regulatory Elements in Prokaryotes & Eukaryotes in chapter Promoter and Regulatory Element Prediction of Bioinformatics
Answer» Right option is (d) regulatory elements Explanation: The regulatory elements may bind in the vicinity of the promoter or bind to a SITE several HUNDRED bases away from the promoter. The reason that the binding of the regulatory protein at long distance can still exert their effect is because of the flexible structure of DNA, which is able to BEND and exert its effect by bringing the transcription factors in close contact with the RNA polymerase COMPLEX.
