Which type of transcriptional termination requires formation of a stem loop secondary structure in the RNA?...
Which type of transcriptional termination requires formation of a stem loop secondary structure in the RNA? What is the primary factor involved in the termination of RNA synthesis? Is a new nucleotide added to a growing strand of RNA at the 3′ end? DNA and associated histones compose what molecule? Be able to use a codon table to give the sequence of amino acids from an mRNA sequence. I will give you an mRNA sequence; you will indicate how many...

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....

As indicated in the image below, miRNAs usually have imperfect base pairing with their target mRNAs, which leads to translational inhibition (the RISC complex is large, and won't let ribosomes through). On the other hand, siRNAs produced from longer double stranded RNA molecules (e.g. viruses), usually show perfect binding to their target mRNAs, which leads to mRNA degradation by the RISC complex. In 100 words or fewer explain why these two types of inhibitory ncRNAs differ in their mode of...
