ENGL6880 Final

Fall 2017

Part I: Spoken Discourse

Describe and analyze the following exchange from a study group. You decide, from a first pass, what’s noteworthy in this dialogue and demands close analysis. Draw on Curzan, chapter 8 for terms, concepts, and analytical guidance. Draw on your work with discourse markers and elements of conversation analysis (pp 271ff).

Topics possible
- performative speech acts
- cooperative principle
- conversational implicature
- communicative competence
- turn taking and the conversational floor

We don't have any gender or identity data, so those can't be addressed.

- interrupts
- tags
- discourse markers
- phonology, morphology where it appears, syntax

S3: (where are) my questions?
S1: what do, you guys have any questions on that first lecture? [S4: yeah (xx) ] on viruses plasmids and prions?
S3: uh, i tried to match up like um, you know the all the different kinds of viruses viroids plasmids uh trans- posons [S1: posons ] and prions um uh with the different, parts of that diagram like D-N-A replication transcription R-N-A replication [S1: uhuh ] [S4: mhm ] and translation, um so the retrovilus uh virus is the reverse transcription, [S1: right ] R-N-A virus, is just n- deals with R-N-A making R-N-A, [S1: right ] and prions p- proteins making proteins. [S1: right ] or, yeah. and um
S1: or, yeah. [S4: converting ] affecting proteins or changing proteins in some way.
S3: but, transposons D-N-A virus and the plasmids are all involved in, the_ using D-N-A and going, somewhat (somehow) this direction?
S1: right plasmids remember is just a circular D-N-A that's inserted. [S3: okay ] okay? so it's goes_ it starts from D-N-A to R-N-A, to proteins. [S3: okay ] okay uh a D-N-A virus yeah it, um, inserts D-N-A, as its material of... um replication. [S3: right ] right? and then, um it'll go on to to um
S3: but it it goes on to make proteins as well
S1: right it does.
S3: and transposons are sort of mysterious or what?
S1: transposons
S4: yeah i didn't really understand how it moves around the genome (xx)
S3: yeah and, it's really vague
S1: wha- i forget what th- what um
S4: the segments of D-N-A that move from one location to another in the genome.
S3: discovered in nineteen forties but not accepted until later.
S4: yeah
S1: i forget what what i forgot what he said that about it
S4: he said it was like a defective virus, so it can't get into a particle without a protein, i didn't really understand like
S1: i remember when we were talking about there_ remember how we were talking about there're different um phases of like virus tacking if it's um, if it's goes into the lytic cycle or the lysogenic cycle, [S3: right ] right? and like
S4: he didn't really talk about that in class though did he? lytic and lysogenic
S5: yeah he never men- he never mentioned the lytic or the lysogenic
S4: or the lysogenic (xx)
S3: the the terms are mentioned in the lab book but we didn't go over it in class.
S4: right he never talks about it.
S1: okay. well uh the one of them is where D-N-A material is being inserted into the, genome, and then um, it can stay dormant, for a while, which means that it never it_ gets expressed, for a long time after several like replications of the cell. so like, this virus, is being replicated along with the rest of the genome as it, you know what i mean like when the cell divides, and forms two, and then, something in the external environment, signals, the cell_ signals that virus to like, start like, producing its own vi- like taking over the cell and like producing its own virus and things like that. right? [S4: mhm ] so like, that's when i_ that's what immediately what i think of when you say like, it jumps from one part of the of the genome to the other part of the genome. [S3: oh ] do you know what i mean? like, that i- maybe it's a sort of like maybe he's like indirectly talking about um, like the lysogenic versus lytic cycle. do you know what i'm saying? like it [S5: i thought ] can go from, [S4: sounds like it ] different parts of the genome.
S5: but isn't lytic and lysogenic just whether, it dies or not? whether the cell's destroyed after
S1: right. because, in in one condition in one case like, the cell that's gets infected, will explode and like, whatever. right? but like, in another case it could be two or three cells that, after several replications that it does that.
S5: so what does that mean for the transposons?
S1: what like the thing is that like the transposons it s- it says like it jumps from like, from parts of the genome to other parts of the [S5: right ] genome right? and like what i'm saying is that like, during one of th- either the lytic or the lysogenic cycle, either like, one of the cycles when it um D-N-A's inserted is inserted, the cell automatically dies. right? it [S5: right ] automatically jumps to the viru- virus attacks the cell, makes a cell, produces the virus and like the protein coat and explodes right? but in the other cycle what can what it can do is it can in- insert that information, that information can go into the genome, right? and like the cell will_ like the virus will stay dormant. af- and the um, D-N-A may or may not be replicated during the [S3: oops ] next, couple phases and it could be replicated where like, um
