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

In Plasmodium, describe the processing of lysyl-tRNA synthetase transcript, by including the localization within the cell, any processing and packaging in general. Any particles that bind to the mRNA molecules, exchange, any membrane to cross, any functional groups to be added

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)

Unanswered gene has three exons that are 140, 230, and 130 bp, respectively. Intron 1 is 125 bp and intron s 95 bp. How long is the properly spliced mature RNA transcript? 220 500 720 1500

Which RNA polymerase makes TRNA? RNA pol I RNA pol II RNA pol III RNA pol IV

Give correct answer and detailed explanation in typed answer(no handwritten)

Prokaryotic and eukaryotic 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 O Eukaryotes have a pre-mRNA that requires splicing to create a functional transcript O Eukaryotes have simpler ribosomes, consisting of fewer FRNAS

Enzymes in which the catalytic portion is not made of protein include all of the following except: the large ribosomal subunit self-splicing introns peptidyl transferase infectious viroids tRNA synthetase
