The termination of synthesis of the polycistronic mRNA is Rho dependent. The role of the Rho proteins is which of the following?
A. To induce the formation of a hairpin loop in the mRNA
B. To induce the formation of a hairpin loop in the DNA template
C. To weigh down the mRNA, pulling it off the DNA template
D. To unwind the DNA-RNA hybrid, releasing the RNA from the template
E. To knock the polymerase off of the DNA template
Homework Answers
Rho act as an ATP- dependent unwinding enzyme,
The role of Rho protein is to unwind the DNA-RNA hybrid, releasing the RNA from the template.

In rho-dependent transcription termination: the formation of a hairpin in the transcribed mRNA causes RNA polymerase to pause, facilitating termination. rho binds the mRNA, and when it makes contact with RNA polymerase, it assists with the removal of the mRNA from the DNA template. the rho factor binds to the -10 consensus sequence located in the promoter region to terminate transcription. a site within the poly(A) tail is cleaved which signals termination. the 3' untranslated region (3" UTR) is synthesized....

termination factor A bacterial protein called rho factor binds to an mRNA at the rut site it moves along the RNA polymerase in a 5-to-3" direction chasing after the mRNA When it reaches the hairpin loop it removes it and then proceeds to break through the hydrogen bonds holding the RNA-DNA together, which successfully removes the RNA polymerase.

RNA polymerase releases the DNA template. Initiation Elongation Termination A process called clearance or escape. The RNA polymerase holoenzyme binds to the promoter A process called clearance or escape. Reaching a terminator sequence causos formation of phosphodiester bonds to stop. The RNA polymerase holoenzyme is formed. Once bound to the promoter, RNA polymerase begins to unwind the DNA. New nucleotides are added to the 3' end of the growing RNA transcript. The RNA-DNA hybrid within the transcription bubble dissociates New...

13. Why are ribonucleoside triphosphates the monomers required for RNA synthesis rather than ribonucleoside monophosphates? A. Only ribonucleoside triphosphates contain the sugar ribose. B. Ribonucleoside triphosphates have low potential energy, making the polymerization reaction endergonic. C. Ribonucleoside triphosphates have high potential energy, making the polymerization reaction exergonic. D. Ribonucleoside monophosphates cannot form complementary base pairs with the DNA template. E. Ribonucleoside triphosphates are not used, rather all use deoxyriboside triphosphates. 14. How is a mutation in a bacterial cell that...
