- Which of these plays a role in the regulation of transcription in both prokaryotic and eukaryotic cells? Question 5 options: attachment of RNA polymerase to the promoter transcription factors RNA splicing gene operonsa QUESTION 7 Please read the paragraph regarding transcription termination and fill in the blanks with words from the word bank below (not all of the words will be used): Rat1 ATP Adenosine AAUAAA Rho TATA A-site RNA polymerase Uracil Rut site Guanosine Hairpin There are two known mechanisms of transcription termination in prokaryotes. One mechanism requires a protein complex called This protein complex binds to the which is located on the RNA that is being transcribed. This protein complex then moves toward the stalled RNA polymerase complex and unwinds the RNA from the DNA. A second mechanism for termination in prokaryotes requires an RNA termination sequence that contains a secondary structure called a followed by a string of nucleotides. Transcription termination for RNA Polymerase II in eukaryotes happens when the termination consensus sequence, is transcribed leading to cleavage of the mRNA 11-30 nucleotides downstream of the termination sequence. Once cleavage occurs, binds to…Transcription factors bind to: Question 20 options: DNA regions called cis-acting elements RNA regions called trans-acting factors DNA regions called trans-acting elements RNA regions called trans-acting elements RNA regions called cis-acting elements
