Above are illustrated the critical segments of precursor mRNA sequence that are involved in spliceosome mediated RNA splicing. Which two nucleotides are joined bythe first transesterification reaction in the first step of the splicing mechanism? <INPUTTYPE=\ c and d<INPUTTYPE=\ a and ex<INPUTTYPE=\ b and c<INPUTTYPE=\ a and c<INPUTTYPE=\ a and b Question 6Which of the following statements about alternative splicing are true? Question 7Hydrophobic residues located at precisely interspaced intervals alignedalong an extended α-helical region which are responsible for homo-

and heterodimerisation are characteristic of which transcription factor (s)? More than one answer may be correct, so you may select multiple responses. You will lose partial credit for each incorrect response selected, and gain partial credit for each correct response selected. <IN PUT TYP E=\ all dimeric transcription factors <IN PUT TYP E=\ zinc finger transcription factors <IN PUT TYP E=\ Gal4 x <IN PUT TYP E=\ leucine zippers transcription factors x <IN PUT TYP E=\ HLH transcription factors Question 8Poly(A) polymerase is required for the formation of the poly(A) tail. To perform its task, poly(A) polymerase has the following characteristic:<INPUTTYPE=\ It tightly binds to the downstream poly(A) signal in the RNA transcript. Question 9Which of the following is/are true? You will be penalized for wrong answers.

<IN PUT TYP E=\ a) The spiceosome proteins are conserved in eukaryotes and prokaryotes. <IN PUT TYP E=\ b) The Ran GTPase efficiently hydrolyzes GTP to GDP. c) NLS and NES sequences are added post-transcriptionally to proteins based on their function in the cytoplasm or nucleus (or both). xd) During splicing, snRNAs base pair with pre-mRNA View Feedback Which of the following is not involved in alternative splicing in eukaryotes? More than one answer may be correct, so you may select multiple responses. You will lose partial credit for each incorrect response selected, and gain partial credit for each correct response selected. <IN PUT TYP E=\ RNA binding proteins <IN PUT TYP E=\ the spliceosome <IN PUT TYP E=\ hnRNPs x <IN PUT TYP E=\ self-splicing group II introns
