How would a molecule of RNA polymerase II be directed to its final destination?It would have a signal sequence on its N terminus that would be recognized bya)a signal recognition particle (SRP) in the cytoplasm that would dock it on theendoplasmic reticulum.O b)It would be synthesized in the endoplasmic reticulum, processed in the Golgiand sent to the nucleus in appropriated tagged vesicles.c)It would be synthesized on free ribosomes, with a nuclear localization sequencethat would facilitate its passage through a nuclear pore.It would be synthesized on free ribosomes, with a mitochondrial localizationd)sequence that would be recognized by a receptor on the mitochondrialmembrane. To get to their location in eukaryotic cells, the genes coding for enzymes involved inglycolysis ..a) must include a nuclear localization signal.O b) must include an ER signal sequence.c) will not include a signal sequence.d) must include a mitochondrial signal sequence.

Ribosomes are the cellular organelles whose function is the synthesis of proteins. Protein…

In the trp operon, if a mutation occurred in the gene for the repressor so that it could bind to the operator even in the absence of tryptophan____________. a) the inducer cannot bind trpO, so operon gene transcription occurs b) the active repressor cannot bind trpO, so operon gene transcription is attenuated c)the active repressor binds tpO, so operon gene transcription is always repressed d) the repressor binds the corepressor, and operon gene transcription occurs.

A newly identified protein from the cells of the Panopyra plant on Pandora was shown to inhibit translation of its target genes by binding to the 5’ UTR of the mRNA and preventing ribosome binding. A possible way this inhibition may be relieved by an sRNA would be: Group of answer choices a)The sRNA acts as a silencer, suppressing the inhibitory protein and allowing translation to take place. b)The sRNA acts as a decoy, sequestering the inhibitory protein and allowing translation to take place. c)The sRNA acts as a marker, flagging the inhibitory protein for ubiquitination and allowing translation to take place.
