3) 17.2, 17.3, 17.4 (315-326) A. Describe the transcription of messenger RNA on the DNA template. RNA polymerase promoter transcription factors transcription initiation complex TATA BOX terminator B. Discuss the process of RNA processing . 5’cap poly A tail intron exon snRNP spliceosome C. How does the existence of ribozymes alter our view of enzymes? D. What importance does the author ascribe to introns? domain E. Describe the structure and function of transfer RNA F. How is a transfer RNA matched to its specific amino acid? aminoacyl-tRNA synthetase G. Find the complementary DNA, mRNA, and amino acid sequence of the following DNA sequence (use table on pg 314) TACATGCCAATT A) Transcription of mRNA - RNA polymerase binds to promoter , which is a few dozen nucleotide pairs and a start point. This initiates where RNA synthesis begins and determines which DNA strand will be used as the template. -In the promoter is the TATA box . A TATA box starts with sequence TATA. A Transcription factor has to bind onto this box (along with other transcription factors binding elsewhere) in order for the RNA polymerase to attach. -The RNA Polymerase unwinds DNA and binds bases to the template strand of the DNA. These new bases will make up the mRNA strand. -The RNA polymerase will move down the template strand of DNA, and add on bases.
