Answers
Which statement about selective gene transcription in eukaryotes is not true? a. Different classes of RNA polymerase transcribe different parts of the genome. $b$. Transcription requires transcription factors. $c .$ Genes are transcribed in groups called operons. $d .$ Both positive and negative regulation occur $e .$ Many proteins bind at the promoter.
Would statement about selective gene transcription in UK rights is not true. Well, uh, one that easily stood out to me was C because C states that genes are usually transcript as groups called operations. However, this is not to be confused with pro Kerry. It's in precarious. You have ah, bronze, But in new carrier to do not. And so is incorrect to say that genes are transcribed in operas because you could simply don't have a bronze. Yeah, you Curiel! Sorry, don't have operations. Thank you for watching. And I hope this helps.
In this problem, we're going to categorize some statements about the central dogma. So the central dogma is a concept in microbiology that says that D. N. A. Is transcribed into M. R. N. A. And then translated into proteins. So DNA is sort of the static information holding material. M RNA is the temporary transcript that is used to get out of the nucleus and then protein is the final sort of useful product of little cellular machines in the cell that do things. So we have two steps here. The first step is transcription of DNA to M. R. N. A. And the second step in sequence is translation translating Mariana into protein. Let's organize all the words in our answer choices and see which ones are associated with transcription and which ones with translation transcription happens because a preliminaries enzyme and already preliminaries enzyme binds to the DNA at a location called a promoter and transcribes the MRNA transcript and then finishes at a place called the terminator. So all those words are associated with transcription. Translation happens out in the cytoplasm when ribosomes and T. R. N. A. Come together and the TR nasR sort of adapters that helped translate between the amino acid language of proteins and the code on language of MRNA. So a code on is a sequence of three nucleotide basis like a U. G. And that codes for a specific amino acid such as the signing. Now that we've laid out all this vocabulary, we can see which word in which answer has a mismatch. So in c we note that we're talking about translation but translation does not involve a promoter. A promoter is something that is involved only in transcription. So that's associated with transcription of Marnie.
What is something false that we can say about selective gene transcription that takes place within new corrodes? So something false that we can say with regards to selective gene transcription, that takes place with the new Kerasiotes is jeans are usually transcribed as groups called operations. This is false because op bronze usually operate in precarious.
Already. So Chapter 17 problem fours checking in the most of these features of Arnie processing. And so one thing to note here is if we are in the nucleus so this be the nucleus If we have our d n a How'd you get that double helix action? Uh, since his DNA that gets transcribes can description into free m on it, right? And so the pre m r in a is made up of both in John's and Exxon's. So this is the pre m r. Okay. And during the war, in a processing. So the next step is on a processing The in Tron tze gets placed out and you're left with just the Exxons right side attendant thing. It was like the Exxons exit the nucleus Eso that point then we have just r m r n a which has no entrance in it and that is what will leave the nucleus. Okay, so it's not the Exxons that air cut out, but the introns are cut out. Esu The answer here for what is not true is going to be letter a
