end of year: high a / a+

[HERculina]

also, for the DNA apart from mtDNA, did you have to specify a particular part of nuclear DNA??
Like Y chromosome or hypervariable regions??
not sure if i did

yea i just wrote nuclear DNA too. But then again why did they put two whole lines for us just to name another DNA?

don't think so. the way the question was phrased, it sounded like it need a one word answer. i elaborated a bit on "chromosomal DNA" because there were two lines, but didn't mention a specific section

I think it would be reasonable for them to expect more detail than chromosomal DNA - so I would not expect to get a mark for that, although you may get lucky.

What if you said "Nuclear DNA to identify the changes/mutations in the sequence, to allow tracing down evolutionary lines and to trace ancestry." As you can tell it was a bullshit answer, but specific enough maybe?

[pezz619]

Would hyper variable regions in nuclear DNA be correct??

I would think so

What study score would I be looking at with a 65 on the midyear, a high A+ in sacs in a good cohort and around 69 on the end of year exam???

[jenerator]

will i be awarded the mark if i answered my questions using percentages instead of ratios? eg. in question 2 , where u had to draw a punnet square

[Namit]

Yeah cause they didn't specify what they wanted  

[TheEscapist]

Yes VCAA always allow answers in percentages or any form of a probability.
Can someone also explain Question 20 from MC to me...I dont understand how option D is incorrect where option A is right.
Could be something i'm missing, I needed all the marks i could get.

[cricketstar]

hmmm yeah I was wondering the same thing..........

[lexitu]

Both are reproductively active - just achieve this through different ways - that option never implies that they are incompatible.
