MBG 3040 Midterm Exam Practice Questions and Answers Where does RNA pol I act? What does it make? - ANSWER-nucleolus, rRNA (most cellular RNA synthesis) Where do RNA pol II and III act? What do they make? - ANSWER-in nucleoplasm; Pol II makes hnRNA, miRNA (controls gene expression), and snRNA (hnRNA becomes mRNA w/ snRNA's help); Pol III makes tRNA (as well as 5s rRNA and others) and has the least activity How many subunits do the RNA pols have? How many in common? Which ones? - ANSWER...

MBG3040 Midterm Exam Questions and Answers How many eukaryotic RNA polymerases are there? What are they called? - ANSWER-3- RNA polymerase I, II, and III Where does transcription and pre-mRNA processing occur? - ANSWER-Nucleus Where does translation and protein modification occur? - ANSWER-Cytoplasm Where is RNA Pol I found and what is its main function? - ANSWER-- nucleolus (suggests txn of rRNA genes) - accounts for most cellular RNA synthesis Where are RNA Pol II and III found? - ANS...

CMB2001 Exam Questions With Verified Answers. Core Promoter Elements - answerTATA box = repetitive sequence of thymine and adenine Initiator (INR) = sequence of pyramidines like thymine and cytosine DPE = downstream promoter elements found along the DNA Common to have >1 promoter but not all of them CpG islands - answerSequences high in CG frequency. They are able to escape methylation which would lead to gene silencing. Demethylation would lead to over expression of genes. Regulatory...

This is a summary of the central dogma of DNA (replication, transcription [in prokaryotes and eukaryotes], and translation [in prokaryotes and eukaryotes]). Some more specific parts included are Rho Independent/Dependent Termination, TBP box, chromatin remodeling, 5' capping, 5'-2' splicing, polyadenylation, alternative splicing and its impact on the regulation of sex within fruit flies, protein structures, code mutations, charging of the tRNA, initiation, elongation, accommodation, and term...
