Accepted Answer

Hi, everyone. Let's look at our next question. It says for you carry outs. D N A is located inside the nucleus. How does the cell bring the genetic information from the nucleus to the cytoplasm where the production of amino acids takes place? Well, we have that whole process DNA to RNA to protein, that genetic code. So as we know DNA is in the nucleus, protein synthesis in the cytoplasm. What's the bridge point there? And that would be choice B through M R N A transcription, the M RNA is transcribed in the nucleus, but once it's transcribed in the nucleus, it gets spliced introns spliced out its five prime cap, it's poly a tail and then it goes out from the nucleus into the cytoplasm. So that M RNA traveling from nucleus to cytoplasm is that bridge between genetic storage and D N A and the nucleus and protein services out in the cytoplasm. Let's just take a quick look at our other answer. Choices. Choice A says through T N A T RNA production. Well, tr nasr transcribed in the nucleus and move out to the cytoplasm but just like M R N A but they're not bringing the genetic information from nucleus to cytoplasm. They're just bringing themselves and then out in the cytoplasm fulfill their role in protein synthesis by bringing amino acids to the rib zone as the new peptide is synthesized. So there, although they do move from nuclear cytoplasm, they're not part of the transport of genetic information in that direction. So that's why choice is not the correct answer. Choice. C says through R RNA generation, um R R N A s are synthesized in the nuclear Elise and then go out to the side of plaza. But like T RNA, their role is not in transporting genetic information, but they form a complex with ribosomes that is that factory where proteins are synthesized. So their role is in being a translation factory, uh not in that movement of genetic information. So that's why that's not a correct answer. And finally choice D through DNA synthesis, that's the replication of D N A but that takes place solely in the nucleus. So that's why that's not our answer choice. So again, for you carry outs DNA located inside the nucleus, how does the cell bring the genetic information from the nucleus to the cytoplasm? And that's choice B through M RNA transcription.
