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...

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....

Eukaryotic messenger RNA undergoes several processing steps after transcription before it binds to ribosomes as the template for protein synthesis. One of these steps is polyadenylation. Identify whether the statements below about polyadenylation are true or false. A polymerase adds a polyadenylate tail of about 10 nucleotides to the 3' end of the mRNA. A polymerase adds a polyadenylate tail to the mRNA while it is still in the nucleus. The polymerase forming the polyadenylate tail uses a polydT DNA...
