I HAVE USED THIS ASSIGNMENT! IF YOU USE IT YOU WILL BE CAUGHT! Homework Assignment-9 Due on Monday, 11/108/10 Question I.    Circle the letter of the correct answer.  The following is a list of elements that are  commonly found in eukaryotic protein-coding genes.  Arrange these elements in the order they  would appear in a gene and in the direction traveled by RNA polymerase along the gene.  Assume that the gene’s single intron interrupts the open reading frame.  For the sake of  simplicity some of the terms are abbreviated and do not distinguish between elements in DNA  versus RNA.  For example, “5’ splice site” is an abbreviation for “DNA sequences transcribed  into the 5’ splice site” because splicing takes place on the gene’s RNA transcription, not on the  gene itself.  1. 5’ splice site 2. 3’ UTR 3. promoter 4. stop codon 5. nucleotide to which the methylated cap is added 6. initiation codon 7. transcription termination site 8. 3’ splice site 9. 5’ UTR 10. poly(A) addition site 11. splice branch site a) 3, 5, 9, 1, 6, 11, 8, 2, 4, 10, 7 b) 6, 3, 5, 1, 8, 11, 9, 2, 4, 7, 10 c) 3, 5, 9, 6, 1, 11, 8, 4, 2, 10, 7 d) 5, 3, 9, 6, 1, 8, 11, 4, 2, 7, 10 e) 3, 5, 1, 11, 8, 6, 4, 9, 2, 10, 7 Question II.    Short answer. 1

1.  Prokaryotic sigma factor and the eukaryotic transcription factor TBP perform critical roles in  transcription. Briefly compare and contrast the roles and modes of action of these two regulatory  factors.  (Answer in 3-4 sentences.)
