Biology Post-exam Discussion

What was the answer to the question which asked about zebra and human dna and gene differences?

[spherelin]

It's transgenic organism because they obtained the genes from another organism. GMO DNA are made artificially in the lab they aren't the same thing.

TMO's are subset of GMO though, as all transgenic organisms have had their genes genetically modified. So wouldn't both be accepted?

[Biceps]

They were asking for the specific type of organism though. I could be wrong.

What was the answer to the question which asked about zebra and human dna and gene differences?

I said that they had a common ancestor very long ago and by now the genes had a lot of variation.

Could you say that they have the same gene for pigment, but different alleles, thus resulting in variation within the gene?
I didn;t write common ancestor because it said 'zebra-fish' not 'zebra' so i thought having a 70% identical gene is unlikey...

Well, if you go back far enough, every organism on the planet has a common ancestor 

Yeah, I said that the gene had been conserved in the two species since their divergence from a common ancestor, but that mutation had occurred since, leading to changes in its base sequence between the two species

Pretty sure God created fish, birds, land animals and humans separately

We have a 50% same genome as bananas. Some genes remain and just become very different over time. Especially if mutations happen a lot more in non-coding regions.

congratulations to everyone who did the exam !!
Be very proud of yourselves !!!

I don't think this has been mentioned yet, but does anyone reckon they'll give everyone marks for question 16 MC?

A and C are clearly wrong
But B and D could both work
The action of waves and currents determines the sedimentation on the corpse, and the hard parts means that it fossilises easier

If there were to be two correct answers then they would accept two correct answers not give marks to people who got it wrong

Yeah true. But would you agree that there ARE two correct answers?

Im not entirely sure but now that I look back...

Never had a problem with the words but i guess ESL students do find it a lot harder. This should be taken into consideration when applying for uni in my opinion...

Try taking your exam in russian and see if that changes, hey ?

LOL
yeah, I don't know other uni but for UoM, the ATAR requirement is lower
Eg: you guys need > 99 ATAR to get into biomed while I only need >95 ATAR

I thought ESL students were allowed English->X dictionaries, where X is a language of their choice?

eg. a English->Chinese dictionary

Really? This is interesting. Where'd you hear this?

I had a quick look through the VCAA handbook and couldn't find it.

No one should do any worse in a *biology* exam because they're an ESL student. I think they should pay more attention to the words they use for these kind of things.

Except for maybe stature though (which just means height) it doesn't seem like any of those words would have an impact on the question thankfully.

Nope, dictionary is only allowed in eng exam. Other subjects we do the same as local students
Luckily the word "stature" doesn't affect the ans but other words make me crazy

[niki]

I'm also an ESL student, but i guess its fair enough that they don't let a dictionary in, we, ESL kids just have to study the words before hand !
