What was it like, do tell.

Also if somebody acquired a copy of the exam, some of us are curious!

Charmz kindly scanned the exam (so be sure to thank her) and you can find it here

Connect Education provided suggested solutions which are available here. Discussion on them will take place from here onwards in the thread

Hmm

I didn't find it too bad, but what did you guys say for where RNA polymerase is found? I didn't know whether they were referring to a structure listed or an organelle (nucleus)! Even my biology teacher said it was terribly worded.

The pedigree for the horses which said the lethal alleles were homozygous was super lame because I couldn't tell if it meant homozygous recessive or homozygous dominant or both. I also think I got 2 or 3 of the MC wrong. Overall a reasonably easy exam but IMO there were a few tough questions. Also I said the RNA polymerase was found in the nucleus but that was another shoddy question.

Someone upload please! Wanna see this!

Harder than last year guys?

[Base]

I'd say it was about same as last years.

What structure did everyone say for the RNA Polymerase?

[Kaylain]

I assumed the lethal allele combinations were homozygous dominant AND recessive so I got 50% and 75% respectively :S

SAME
last years was piss easy though..

 ^   I said strand G only because I thought we needed to use something already labelled. Otherwise I would've gone with nucleus. :/   I think I assumed homozygous recessive was lethal. Damn.

Nah that question had terrible wording as well and I thought it was quite troublesome they made us construct a dihybrid cross/Punnett Square just to find 2 probabilities for 2 marks

I hate you VCAA and your ambiguous questions.

-_-

[bawse]

Ran out of god damn time. I didn't think it was too hard, but because of poor time management I've messed up my mark... hope I can at least scrape a C for it.

did we have to construct a punnett square?

What was the other type of DNA you could use aside from Mitochondrial DNA?

[Base]

Also can someone clarify this:

The question that had to do with the HERDA trait, was the Heterozygous female crossed with a Heterozygous male or Homozygous male?
