Question

each molecule has a specific shape and specific binding site on the a. transcription factors bind to the b region of dna. activators bind to the c region of dna. rna polymerase binds to the d region of dna. the enhancer region of dna is located e of the promoter. when all molecules are bound to their correct locations on the dna, the dna bends to bring the f close to rna polymerase. true or false: transcription of mrna is only dependent upon the binding of rna polymerase to the promoter. g

Explanation:

In gene - expression regulation, molecules bind to specific DNA regions. Transcription factors bind to the promoter. Activators bind to enhancer regions. RNA polymerase also binds to the promoter. Enhancers can be upstream or downstream of the promoter. When all molecules are bound correctly, the DNA bends to bring the activator - bound enhancer close to RNA polymerase. Transcription of mRNA is not only dependent on RNA polymerase binding to the promoter but also on other factors like transcription factors and activators.

Answer:

A. Protein (molecules bind to proteins in general context of molecular interactions)
B. Promoter (transcription factors bind here to initiate transcription)
C. Enhancer (activators bind to enhance transcription)
D. Promoter (RNA polymerase binds to start transcription)
E. Upstream or Downstream (enhancer location relative to promoter)
F. Activator - bound Enhancer (DNA bending brings enhancer close to RNA polymerase)
G. False (multiple factors are involved in mRNA transcription)
