The accessibility of promoter regions of bacterial DNA in many cases regulated by the interaction of proteins with sequences termed

Assertion :- The activity of RNA polymerase at a pormotor is regulated by interaction with accessory protein, which affect its ability to recognise start sites. Reason : The accessibility of promotor ragion of prokaryotic DNA is in many cases is regulated by interactin of proteins with operators.

In a transcription unit, the activity of RNA polymerase at a given promoter is in turn regulated by interaction with accessory proteins, which affect its ability to

The region of DNA sequence that provides binding site for RNA polymerase is :

Regulatory proteins are the accessory proteins that interact with RNA polymerase and affect its role in transcription. Which of the following statements is correct about regulatory protein ?

The lac operon consists of a regulation gene and three structural gene. The lactose acts as inducer. In the presence of an Inducer such as lactose, the repressor is in inactivated during the interaction. This allows RNA polymerase access to the promoter and transcription proceeds. The repressor is synthesized which in turn binds with the operator region of the operon and prevents RNA polymerase from transcribing the operon. Identify the correct sequence of the structural genes in the lac operon.

The DNA sequence that provides binding site for RNA polymerase in eukaryotes is

Assertion : The predominant site for control ofgene expression in prokaryotes is transcription initiation. Reason : The activity of RNA polymerase is regulated by accessory proteins, which affect recognition of start sites.
