When comparing prokaryotic RNA polymerase with eukaryotic RNA polymerase II, only eukaryotic RNA polymerase II
begins by binding to the gene's promoter region.
uses sigma factor to specifically recognize promoter consensus sequences.
relies on a collection of transcription factors to facilitate its binding to the DNA.
begins transcription at numerous origins of replication.
uses a double-stranded DNA template to produce a single-stranded RNA copy.
Homework Answers
Answer
only eukaryotic RNA polymerase II relies on a collection of transcription factors to facilitate its binding to the DNA and prokaryotic RNA pol II does not require transcription factor to bind over promoter.

Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...

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....

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...
