GENERAL GENETICS (HIOL 2510) WINTER QUARTER 2018 EXAM #4 (100 points) 30. Which of the following statements regarding transcription is NOI true? NA polymerase transcrbes the template strand of DNA into RNA is complimentary and antiparallel to the template strand L RNA synthesis i m. RNA polymerases require a free 3-OH n. RNA polymerases have limited a. RNA synthesis aways occurs in the 5 to 3 direction. group to initiate transcription. 31. Use the fgure below to answer the following questionnds ot the branch point. Binding of is the snRNP that initially binds at the 5 consensus sequence. In contrast initially s a prerequisite for recruiting and forming a function spliceosome at this intron Exon 1 5splice site 3'splice site Branch 3'consensus sequence a. U5, US b. U5, U2 c. U1, U6 d. U1, U2 e. U1, U4 32. The processing of the 3' end of a eukaryotic mRNA involves binding of to the poly(A) signal (consensus sequence -AAUAAA). First, this protein will help stimulate cleavage at a site approximately 11-30 nt downstream of the poly(A) signal. Second, it will recruit polymerase that is required to promote the addition of adenine nucleotides at the cleaved 3' end. an RNA R a. CPSF, PAP b. PAP, CPSF c. CPSF, RNA Pol II d. PAP, RNA Poly II e. CPSF, PABP 33. A long poly(A) tail is generally associated with very low levels of translation. p. true q. false 34. The catalytic component of the spliceosome is the SnRNP a. U1 b. U2 c. U4 d. U5 e.
