Based on your knowledge of the mechanism of gene silencing by double stranded RNA, identify the component labeled 'A' Group of answer choices RISC Dicer Transcription activator Enhancer
In eukaryotes, why is the initial RNA transcript usually longer than the mature mRNA molecule? Group of answer choices Because a guanosine cap has to be removed Because exons have to be removed Because a poly-A tail has to be removed Because introns have to be removed Because the RNA primer has to be removed
All of these are mechanisms of eukaryotic RNA processing except: Group of answer choices The splicing of introns. The placing of a poly A tail. The placement of a 5' cap. The placement of a 3' cap.
Addition of 3’-CCA to tRNA is an example of which of the following? Post -replicational modification Post -transcriptional modification Post -translational modification Reverse transcription Polymerase chain reaction
The antibiotic kasugamycin blocks the binding of methionine to tRNA. From this information, you can conclude that kasugamycin prevents: transcription in prokaryotes mRNA-ribosome binding in eukaryotes the synthesis of ribosomes by rRNA in eukaryotes the initiation of the synthesis of a protein in prokaryotes e. RNA polymerase from binding to a promoter
What is substitution RNA editing ?
Which of the following is false? Options: tRNAs are heavily processed but in a manner that is different than mRNAs mRNAs are protected from degradation by modifications at the 5' and 3' end rRNAs are all cleaved from a larger pre-rRNA precursor Group II splicing requires protein and RNA to excise intron sequences methylation of histone 3 at K4 results is mostly associated with activated transcription
One fundamental difference between transcription in prokaryotes and eukaryotes is: eukaryotic RNA transcripts undergo polyadenylation (poly-A tail; cap) eukaryotes produce single RNA transcripts called operons that code for several proteins prokaryotes undergo capping of their 5' end of the RNA transcript prokayotic transcription occurs in the nucleus O prokaryotes have intervening sequences that are spliced during processing of the RNA transcript
Which of the following sequences would most likely be the site of the initiation of transcription? ТАТАААТА GCTAGCTA GGCGGCCC Impossible to tell
What is the eukaryotic mRNAs modification at 5' end? options: poly (A) tail. guanosine cap pseudouridine acetylated nucleotides
This type of mutation, where one nucleotide was replaced for another, is called a point mutation. White skin and blue eyes are examples of point mutations.Provide the mRNA that will be made from the mutated strand : 3' TAATATATCCGTACCGTTTAAAGGGTTACATAATTTTTCATCCCATTA5'
In eukaryotic transcription, which of the following is not included in the initiation of transcription? Group of answer choices RNA polymerase II TATA box Holoenzyme AAUAAA consensus sequence
