The correct answer is-
A- hairpin; rho
This is because hairpin loop is the termination sequence for transcription as once a polymerase meets this loop, it falls off and transcription ends. Also Rho terminates the process of transcription in response to specific DNA signals transcribed into RNA called the rho-dependent terminators.

Transcription is terminated, when a characteristic RNA structure _____ is formed by local RNA palindromic sequences at the 3’- end. The structure interacts with RNAP-bound NusA, causing dissociation of RNAP from template DNA. The RNAP dissociation is stimulated by sequence-specific binding of _____ proteins to the transcribed RNA, enhancing termination of transcription. Select one: a. hairpin ;;;; rho b. hairpin ;;;; sigma c. beta-turn ;;;; rho d. beta-turn ;;;; sigma e. None of these
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....
In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...
Here is all the information and content! One of the questions which shows a double stranded sequence and asks for the mRNA sequence has not correct answer. It should be dropped. Anyone who majored in Bio can answer these 2nd-year biology multiple questions (only Q14 has more than one answer). Thanks a lot!!!!! Question This type of RNA does not participate in the splicing reaction, but is important for efficient functioning of the spliceosome. Not yet answered Marked out of...
