    sure.

    a CF sufferer has found out that the only hope for his survival is the use of stem cells to code for the CFTR protein, however, he is very apprehensive and reluctant to undergo such treatment even though the doctor has explained to him all the cons about this type of research..

    Explain one of the points the doctor has told the patient.. (2 marks)
    Give 2 reasons why the patient is reluctant to take part in stem cell research. (2 marks)

    Why must stem cell research be closely regulated? (3 marks)

    What are the risks associated with the surgery the patient must undergo? (3 marks)

    I tried to make it exam styled.. sorry if it's not exactly the best thing ever

    Hey guys, i've made a revision resource from loads of different books including the "Edexcel AS Biology revision guide for snab and conept led approaches " by pearson, and the CGP guide, the green chunky new textbook and assasins notes, and some stuff i found from get revising too .

    if i upload it, could u guys check it for any inaccuracies?

    it is quite long, but i think it covers the whole syllabus.

    Here's a copy of my revision word doc.
    please feel free to criticise, comment and highlight what i've missed, done too much of , or got wrong.

    note:
    for the plant structures, refer to the diagrams in the cgp guide- they're pretty good and i couldnt replicate them.

    for the experiments,
    i've only left in what assassin has done, ill add in bits from elsewhere and reupload later if anybody finds it useful

    i've only compiled work from lots of different resources-i dont claim any of this to be mine.

    thanks for assasin for the upload earlier. a lot of this is based on his work before.

    WoW thats really helpful!

    mmm
    one of the points like in the future it ll become possible to clone an entire human ...like that things u mean?
    reluctant coz of possible infection (i.e cancer) ?
    for this question any 3 points from "regulatory authorities" from assasin notes ryt?
    last question :mmmm possible death/ infection/ injury in organ ?
    btw i rlly liked it thx a lot!! :cool:

    Just read the cgp guide or better yet download the unit 2 notes somewhere on this thread

    What's the difference between genetic variety and genetic diversity ?

    - A polypeptide chain is synthesised in a ribosome when peptide bonds are formed between many amino acid monomers; the ribosome is attached to the cisternae of the rER.
    - The polypeptide chain moves into the cisternal space of the rER, where it undergoes further processing in order to achiever a tertiary structure.
    -The rER packages the protein into a vesicle.
    - The vesicle fuses with the cis-face of the Golgi apparatus, thus causing the protein to enter the cisternal space.
    - In the cisernal space, carbohydrate chains are added/trimmed in order to create a glycoprotein, for example, which creates a quaternary structure (not all proteins do this).
    - The Golgi apparatus packages the glycoprotein into a vesicle at the trans-face.
    - The vesicle fuses with the phospholipid bilayer; secreting the protein via exocytosis.

    So they are involved in the processing and packaging of proteins- complex proteins could not be created without them.

    Hope that helped

    Yes. You need to know the names of them and the basics of what they contain and be able to apply it.

    Eukaryotes = membrane bound organelles.
    Bacteria/Archae = no membrane-bound organelles.
