yotic RNAS differ in which of the following ways? FRNA molecules are only part of the prokaryotic ribosome Prokaryotic RNAS have non-coding sequences that are removed during processing Eukaryotes have a pre-mRNA that requires splicing to create a functional transcript Eukaryotes have simpler rihosomes consisting of fouwor rDDLO

Which of the following characterize RNA polymerase Il transcriptional termination in eukaryotes? Endonuclease cleavage of the RNA transcript and 5' to 3' exonuclease activity a protein known as Ratl None of the provided answers, transcriptional termination occurs in prokaryotes. Recognition of the transcriptional stop codon by a release factor. Hairpin structure formation on the newly synthesized RNA molecule which disrupts the DNA-RNA hybrid at a poly-U RNA sequence Binding of the Rho protein.

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

Which one of the following options is NOT a step in RNA processing? Addition of the 5’ G cap Addition of the 3’ poly A tail Splicing to remove exons and connect the retained introns Splicing to remove introns and connect the retained exons

RNA polymerase in Escherichia coli normally synthesizes all of the following molecules except: RNA primers during DNA replication messenger RNA (mRNA) transfer RNA (tRNA) ribosomal RNA (rRNA) heterogenous nuclear RNA (hnRNA)

Spliced introns are recognized and degraded in the nucleus because of their:   Question 10 options:   Unprotected 5' and 3' ends   Branched lariat structure   Leftover SSB proteins still attached to the RNA   Unique tertiary (hairpin) structure   formed intron-rRNA duplexes

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
