Explain how a regulatory transcription factor exerts its effects via TFIID or mediator.

Provide the major molecules and organelles involved in transcription.

What role does an operator sequence serve in bacterial gene expression regulation? Describe one change in bacterial cells that can cause a repressor protein to go from inactive to active or from active to inactive.

A string of 8 adenine nucleotides in the mRNA is required for function of an intrinsic transcription terminator in bacteria. True False

When CAMP binds to the Catabolite Activator Protein (CAP), it causes a conformational change on the protein, which results in binding to the CAP- binding site on the DNA and molecule is known as a(n) of the lac operon. This conformational change induced by the binding of another transcription activation; allosteric effect transcription repression; binding effect translation; distortion effect mutation; interactive effect attenuation; compression effect O O O O
