    Really? The spec just says the formula.
    It'll say something like "the critical value for XX with XX degrees of freedom is XX" - the critical value is almost always seven point something... think it's 7.82.

    i dunno just guessing really.

    but theres always a 7 marker and an 8 marker question in these exams as i read the spec and it said F212 ( Unit 2) and F215 - this unit will have extended writing which means an 8 marker question.

    I couldn't write 7 marks on Golden Rice...I'm hoping for long questions on cloning and/or biotechnology

    Good luck everyone! I'm really struggling to remember everything for this exam

    Is that the agrobacterium tumafaciens stuff? How would you extract the gene?

    just a question on the DRD4 gene, the last paragraph on page 246. if people had the DRD4 receptor that increases addictive behaviours, would i be right to say its because the DRD4 receptor is less responsive to dopamine, so there is less sense of general pleasure or reward so they develop addictive behaviours and take risks more?

    my A2 ones are terrible including the practical (got like 28/40), retaking F214 because i got a D in that -.- , But to get a B overall I need without retaking F214 i need a high D in this exam. Im aiming for an A so kinda really need this F215 exam to go well and the F214 to go good aswell

    Hi everyone.

    Does anyone know the advantages and disadvantages of using ACFOR measurements. I know a disadvantage is that the measurement is subjective but what else?

    Also, what do we need to know about kite diagrams?
    Thanks

    Heyyy just returned from the library, one thing that came up was about stop codons.

    In my OCR Sue Hocking textbook it says the three stop codons are UAA, UGA and UAC.

    However in the Heinemann revision guide it says they are UAA, UGA and UAG.

    :eek3: Which is it?

    You can talk about how transformed plants are "made"

    Psy gene (dafodill)
    ctrl gene (bacterium)

    Then all the restriciton enzymes/plasmid/marker genes all apply aas they do in genetic engineering.

    Golden rice is just genetic engineering rice to produce beta carotene, so just talk about genetic engineering! ...i could see a big mark question on it coming up:yep:

    I would say the opposite, increased sensitivity increased pleasure leading to addiction.

    Advantages: No test required, quick to assess

    Disadvantages: Opinionated making it hard to compare results

    hmm i doubt they will ask you to name all 3 stop codons so jsut stick will UAA and UGA
