How do activators facilitate transcription? Activator (inactive) Activator- binding site RNA polymerase Promoter Transcription normally off. RNA polymerase cannot bind to the promoter unless the activator is bound to the activator-binding site, but the activator is in an inactive form. Inducer Activator (active) Inducer helps turn transcription on. NNNNA Transcription Inducer binds to the activator and changes its shape, allowing the activator to bind to the site. RNA polymerase can then bind to the promoter and initiate transcription.

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
Identify the DNA elements and protein factors, #1-7, in the figure below that are involved in the initiation and elongation of transcription at a eukaryotic promoter of a gene TRANSCRIPTION ON RNA PROCESSING PefA A eukaryotic promoter commonly includes a TATA box (a nucleotide sequence TRANSLATION Ritoom containing TATA) about 25 nucleotides upstream from Nontemplate (coding) strand of DNA 7 Pupeptide 1 the transcriptional start point.

A bacterial species has a hypothetical sigma promoter that has the following sequence: TTGGCA - 18 bases - TATAAT What change in the level of transcription would there be if the sequence was mutated to: TTCGCA -18 bases -TATAAT O The mutation would bind the promoter to the consensus and produce normal levels of transcription O The mutation would inhibit the promoter thereby inhibiting transcription The mutation would move the promoter away from consensus and reduce the level of transcription O No change the consensus TATAAT sequence in the same.
