Agreed with what toilet said but not exactly how I would have typed it lol.
Definitely don't need to know as many specific details but I don't think that is their intention when writing out the exam.
I think they're starting to put more of an emphasis on concepts etc in CELS. For example last year we had to know that whole process with the mice and genes and stuff. But this year your lecturer told you that you don't need to know that, only understand why it's there.

But sometimes it helps to put specific details if it's relevant to the question, to show the examiner that you are BAWSS.

[OFFTOPIC]Surprisingly, you guys say eh more than Canadians do[/OFFTOPIC]

That's a fair standpoint; looks like I should have rote learned after all XD

Is forward genetics finding the gene/sequence causing the phenotype, and reverse genetics finding the function of a gene?

Yup. Make sure to remember the processes for each one (Heidelberg Screen for forward and Knockout Mice for reverse). Good luck tomorrow!

Thanks! You too!!!

 

[Sam]

Thanks! You too!!!

Heh, turned out to be very relevant

Easiest CELS191 exam ever?

 

[Swaghilli]

That was PRETTY easy. It's really nice how this final incorporated some questions from past exams.

 

[SeeKay]

Yeah this year was more conceptual than other years I think.

 

[marsupial]

Wow I've never heard any health scis describe ANY exams as being EASY. Glad it went well for you guys! Two more to go!

 

[Wongtong]

I agree that it was pretty good.

What did you guys chuck down for that question about aneuploidy in short chromosomes?

 

[Caesar]

That question was such a pain. I put that because they're short they contain less genes and therefore the relatively small extra "dose" of genetic material wouldn't cause a disturbance in development so great that it would stop it completely, like the ones of longer chromosomes would.

I am beginning to regret this now.

I'm only looking at 70-75% at best guess.. but for no study other than a quick flick through the lecture slides, that seems like an easy exam.

Why would you regret putting that down? Most people that I've talked to put something along the lines of that.

I interpreted it differently and put something about spindle fibres not being able to find the right place to attach to :S haven't really met anyone else who said the same thing as me.

 

[frootloop]

[MENTION=5278]Caesar[/MENTION]: I wouldn't regret putting that down, sounds more or less right to me. Aneuploidies in the bigger chromosomes tend to be more likely to auto-terminate early in development, as they're getting more (or less) extra genes, so creates more of a problem. Which is why the only aneuploidies which usually survive to term are ones of the smaller chromosomes, like the classic example of trisomy 21. (I'm assuming the question was about why aneuploidies 'appear' to occur more in smaller chromosomes?).

 

[marsupial]

[MENTION=5278]Caesar[/MENTION]: Yeah I agree with Froot. That's pretty much the whole idea. I would've been happy with putting that answer down.

I did this too! LOL

... and my other reason, is SOOOO DUMB, that I'm not even going to like share it. I feel like the biggest idiot in the world ><

 

[Profiterole]

Is it just me or other people disappointed that they didn't have the usual recombinant question? (i,e draw they dihybrid cross, explain it, find the length?)

 

[Wongtong]

(I'm assuming the question was about why aneuploidies 'appear' to occur more in smaller chromosomes?).

Yep, it was pretty much that. I think my (mis)interpretation came about because I thought they meant aneuploidy occurred more often with smaller chromosomes in general [both spontaneous abortions and live births].

Is it just me or other people disappointed that they didn't have the usual recombinant question? (i,e draw they dihybrid cross, explain it, find the length?)

Yeah, that was a bit mean. I saw the question and instantly thought it would be something to do with incomplete linkage but then I noticed the 9:3:3:1 ratio.
