Describe the structure and function of elements needed for transcription, including the promoter, RNA polymerase core...
Discuss major components and events in RNA processing, including introns and exons, splicing, the spliceosome, the 5'G-cap, and poly(A) tail. Describe tRNA structure and function, including how amino acids are attached to tRNAs and how codons are read. Discuss mechanisms for translation initiation, elongation, and termination.
-Stages of transcription (in detail for each step) - what components are required -Modifications of RNA (on the ends of mRNA, on the interior of mRNA) -why are these modifications important? -Ways to cut out introns (i.e. Splicesomes) -Alternative splicing Translation -TRNA structure and function -What controls accurate translation -wobble effect of tRNAS -general concept of how translation works using mRNA, ribosome, anticodon, tRNA -3 stages of translation (in detail) -initiation -elongation -termination
3. Prokaryotic and eukaryotic gene expression compared. Below is an incomplete table of prokaryotic and eukaryotic gene expression in comparison. Fill in the blank using PPT slides, notes and the textbook. Prokaryotic gene expression Eukaryotic gene expression Overview Steps Transcription and translation Yes Transcription and translation coupled? Gene structure No introns Epigenetic modification (chromosome remodeling) transcription, translation, RNA processing, protein processing Transcription in the nucleus and translation in the cytoplasm Interrupted gene with exons and introns RNAPI, II, III Which...
1) Which of the following is FALSE about RNA polymerase?It does NOT require a primer to begin synthesis It synthesizes RNA 5’ to 3’ It catalyzes the formation of phosphodiester bonds It only transcribes one of the two DNA strands for any particular gene It only transcribes exons 2)Which of the following is not synthesized from, or does not use DNA as a template? Introns Poly A tail Ribosomal binding site Primase RNA polymerase 3) Which of the following is...
answer all the questions 18) A mutation occurs such that a spliceosome cannot remove one of the introns in a gene. What effect will this have on the gene? Translation will continue, but a nonfunctional protein will be made b) Translation will continue and will skip the intron sequence c) It will have no effect; the gene will be transcribed and translated into protein d) Transcription will terminate easily and the protein will not be made 19. During the process...

Complete the following table with information on the three types of RNA polymerases and role of specific type of RNA in protein synthesis: In prokaryotes, the two stages of protein synthesis are: ___ and ___. In eukaryotes, the three stages of protein synthesis are ___, ___ and ___. During transcription, a ___ ___...
A promotor is used by RNA polymerase during which stage of transcription? Group of answer choices A. Initiation B. Elongation C. Termination D. Promotion 2. In eukaryotic cells, mRNA is modified in several ways. Match the mRNA modifications to their functions. Group of answer choices [ Choose ] Portions of the mRNA that are removed before translation. Helps ribosomes attach to the mRNA. Depending on the length, this structure can help...
The answer should be more than one. Select all statements that describe stop codons. 43 10 Check All That Apply points O U Stop codons bind to release factor proteins. eBook 0 U Stop codons are found in exons. Print References 0 Stop codons are also called nonsense codons. 0 Stop codons are 5'UAA, 5' UAG, and 5' UGA. 0 U Stop codons specifically bind uncharged tRNAs. 0 Stop codons are found in introns 0 U Stop codons code for...
hello, two of these circled answers are incorrect. 1 6. The promoter sequences are the positions that: signal the initiation site of a gene (+1) B) bind the transcriptional factor that is associated with RNA polymerase e) attach the correct nucleotide triphosphate to the template DNA strand D) separate the two DNA strands CUA 7. A particular triplet of bases in the coding sequence of DNA is GAT. The anticodon on the tRNA that binds the mRNA codon is A...
