Yo
if they ask for the pheno and genotype of offspring produced, but they don't ask for the ratios, do you still need to give the ratios? Cause in the suggested solutions you've given the ratios but they haven't asked for them

[Ravit]

they shouldnt mind, unless they are wrong, putting the ratios in would just impress the examiners that you have been reading previous exam reports and are doing what you should be

I think you worry too much bazza. Stop thinking about the exam. It's not like you can do much else to change the result you are going get.

yes he can! he could make threats to vcaa/examiners etc, he totally would

If he hasn't done so already.

ahahhahahaha true

How can we get the examiners to know about some of these issues?? do our teachers tell them or do we ?

[thushan]

Are any of your teachers assessors? If so, tell them and they'll raise it at the meeting.

[Ravit]

email the the chief assessor with any problems or tell any teacher at your school who is a bio vcaa marker to bring it up at their markers meetings.

[Namit]

I'll email 'em.
Because I'm 100% about q3 being DNA replacement because even VCAA mentions in 08 examiners report:
"Gene therapy aims to insert a normal/functioning allele into a cell.
An example of incorrect information provided by students was ‘the removal of an allele or the insertion of an allele into
the body’."

The question said: "Defective alleles may result in genetic defects. Replacement of a defective allele with a normal allele is called:
A- Cell cloning
B - gene therapy
C - Triplet change
D - DNA replacement."

REPLACING a defective allele clearly implies, REMOVING, then INSERTING the allele, and so i dont think gene therapy is right, unless im missing out on something here.

[cricketstar]

yeah, I would be interested to hear what they say.

[A-i-d-a-n-K]

Fucking fuckidy fuck fuck.

That exam was a worthless rag. The RNA polymerase question was just mean. Piece of utter crap.

I'm really desperate here for marks, because I know I've at least lost 6, maybe 7.

For the puppy question, where we had to list the parents genotypes, I was really idiotic and wrote for the mother: BbTt, and also for the father: BbTt. Because it's a really small sample size (only 4 puppies) do you think they will accept two heterozygotes rather than BbTt and bbtt?

I did the same as you for the puppy question. I don't see why they wouldn't accept as those parents could realistically produce those offspring

intriguing

Definition of gene therapy: Gene therapy is the insertion, alteration, or removal of genes within an individual's cells and biological tissues to treat disease

The answer is B, dude

[Namit]

I'm adamant about it! there was another trial exam i did that said similar, ill try and find out which one...

[nubs]

If you're right, the VCAA assessors will mark you as right
They're not idiots, they don't need to be told how to do their jobs by students
