Biology Exam Discussion (and suggested answers!)

[bimberfairy]

That, my friend, is a very good feeling

The wave of relief HAHA

For the Beadle and Tatum, did you guys talk about how knowledge of how certain genes produce certain polypeptides ( and hence proteins) has allowed transgenic species because we can take out specific genes to allow specific proteins to form in the organism?

Yes! I described their findings + explained that + explained process to make Bt cotton and linked parts of it back to finding + explained a bit about how other scientists also contributed to ability for transgenesis

Whoooo I wrote something along the lines of that too! Essentially gene expression (:

What were the other options for Q11? T-cells do form clones don't they

I don't remember but I'm pretty sure memory T are cloned as well as cytotoxic? This is the only one I've gotten wrong according to naomi's results but I'm pretty sure her answer isn't correct.

Was honestly shocked at how easy the MC was, probably easier than any past paper I did. Loved the 8 marker tbh but the 7 marker on hearing technologies was a pain in communication. Never revised the transport mechanisms in phloem or looked over the transverse diagrams of xylem/phloem which I'm annoyed at myself about but other than that it was a pretty easy exam (for biology). What did people put for the question that asked for the genotype of the chromosomes? Wasn't too sure what to put but I just wrote "heterozygous" and i'm not too confident about that haha.

yeah, I thought T cells are cloned too... I picked the option with them both having markers to detect antigens or something like that (i forgot how it was phrased),

[mbdtHSC]

11 should be the option about both T and B having  specific recognition thingos or whatever

Helper T-cells have surface receptor protein specific to antigens and B-cells have MHCII glycoprotein molecules

I'm not sure if my answer for genotype was correct, but I wrote "ABG, abg"

Prepare for a high as fuck cut off this year

Genotype is Aa Bb Gg

But the cell was 3cm across and 1cm = 5um according to their scale. Or am I just an idiot who can't use a ruler ?
And also don't t cells replicate - burnets clonal selection theory and all?
Thanks for posting all of this though!

Ahahaha! Don't worry you aren't the only one

I'm thinking the same thing, I felt like it was C

The scale was 1.5cm = 5um, so 3cm = 10um. Must have misread, unlucky
