Which of the following mRNA processing factors associates with the CTD of RNA polymerase II?
A. Splicing factors
B. Polyadenylation factors
C. Capping proteins
D. siRNAs
Homework Answers
Answer - B. Polyadenylation factors
The recognition of polyadenylation signals may alter the association of processing factors with the CTD, which may cause the polymerase to switch to a termination-competent form.

QUESTION 1 Which of the following statements regarding splicing is FALSE? A) The length of introns determines the efficiency of splicing. B) Many human neurological disorders are caused by splicing errors and/or mutations in splicing factors. C) Splicing requires the action of a variety of snRNAs that direct the transesterification reactions. D) Splicing is dictated by sequence features in pre-mRNA transcripts QUESTION 2 Which of the following mRNA processing factors does NOT associate with...

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...

Suppose a mutation occurs in the gene encoding eukaryotic RNA polymerase I, II, or lll that renders that polymerase non-functional. Match each RNA polymerase mutation with all of the cellular processes that it would disrupt.

Describe in detail the structure of the RNA polymerase II CDT and how the structure is used to sequentially regulate the maturation of the pre-mRNA during the elongation phase of transcription. Focus on the events which happen on RNA polymerase II CDT. For mechanisms which are directly responsible for pre-mRNA processing, you only need to mention their names.
