- The locations of the TATA box in two species of yeast, Saccharomyces pombe and Saccharomyces cerevisiae, differ dramatically. The TATA box of S. pombe is about 30 nucleotides upstream of the transcription start site, similar to the location in most other eukaryotic cells. However, the TATA box of S. cerevisiae is 40 to 120 nucleotides upstream of the start site. To better understand what sets the start site in these organisms, researchers at Stanford University conducted a series of experiments to determine which components of the transcription apparatus of these two species could be interchanged (Y. Li et al. 1994. Science 263:805–807). In these experiments, different general transcription factors and RNA polymerases were switched in S. pombe and S. cerevisiae, and the effects of each switch on the level of RNA synthesis and on the starting point of transcription were observed. The results from one set of experiments are shown in the table below.

- Choose all that apply regarding gene transcription in eukaryotes: Multiple transcription factors are necessary to form the pre-initiation complex (PIC) of RNA Pol II. The 5' cap of mRNA requires the free triphosphate on the nucleotide at the 5' end. Introns must be removed from the initial RNA transcipt. Histone acetylation is a method controlling gene expression. Acetylation creates more positive charges on histones, leading to tighter binding of the proteins to DNA. Exons are removed from mRNA by the spliceosome. RNA polymerase II must completely finish an mRNA transcript before processing can begin. RNA polymerase I catalyzes the synthesis of the majority of ribosomal RNA. The hormone 173-estradiol binds to a G-protein coupled receptor to control gene transcription.arrow_forwardDiscuss and make a list of the similarities and differences in theevents that occur during the initiation, elongation, and terminationstages of transcription and translation.arrow_forwardMicrobiologists describe the processes of transcription and translation as “coupled” in bacteria. This term indicates that bacterial mRNA can be undergoing transcription at the same moment it is also undergoing translation. How is coupling possible in bacteria? Is coupling of transcription and translation possible in single-celled eukaryotes, such as yeast? Why or why not?arrow_forward
- Choose any/all that apply to mRNA processing in eukaryotes. The "starter/initiator" methionine codon is added to the 5' end of each mRNA molecule during post-transcriptional processing. The entirety of every mRNA transcript is always translated to protein. The 5' m'G cap interacts with the 3' poly (A) tail (via initiation factors and other proteins) to circularize an mRNA as part of the initiation of protein translation. mRNA processing occurs while genes are actively being transcribed.arrow_forwardPresent an overview of various forms of posttranscriptional RNA processing in eukaryotes. For each, provide an example.arrow_forwardDescribe the prokaryotic translation initiation shown in the diagram. Define the convention of protein synthesis (directionality of synthesis) as well as the meaning of the A, P, and E sites of the ribosome.arrow_forward
