    Do ya reckon we need to know all the definitions in the textbook? The specification is very specific about which ones to learn...reckon we should just learn the ones in the spec or learn everything?

    Arggggggh! Biology is making me go crazy!

    Anyone learning stuff beyond what is needed for the specification ? I have yet to start proper revision, but would it be a good idea to cover every single point on the spec for revision ? Any other revision tips would be appreciated, thanks.

    I think this paper is giong to be so synoptic with graphs , data and intepretation so be prepared or prepare to fail.

    Woah alrighty:
    Non-reproductive cloning: Here a non-reproducing (cell)genetic anomaly or fault within the cell is fixed.This is usually done by either having the correct allele version sprayed over liposome structure or over adenoviruses.Which is then inserted into the patient which is then exchanged within the lung cells as in CFTR although its effect are temporary lasting few weeks.
    Or perhaps by reversing the working of differentiated cells.
    As for reproductive cloning here a cell body is fused with eunucleated egg which goes onto form a zygote (after mitosis).

    Umm i think covering every point is essential as these OCR bio exams can be unpredictable , but thats just my point of view

    Surely its something more along the lines of 'non-reproductive involves the synthesis of new cells which are genetically identical to the parent organism, whereas reproductive cloning involves the synthesis of a new organismwhich is genetically identical to the parent organism.

    But mine sounds very...lacking in something maybe?

    Dunno, whatdoya think? Its the first bullet point for Chap 9 in the spec and I wasn't too sure how to interpret it / what to write as notes - not much on comparisons in my book or revision guide.

    Basically Non-reproductive cloning (NRC) is the extraction of embryonic stem cells from an embryo at blastocyst level. Thats the most simplistic and yet in-depth definition for it

    guys for the "describe one example of primary succession resulting in a climax community" have you just revised the sand dunes one?

    Also ive revised the plants like sea couch and sea rocket etc, do we really need to revise those?

    I learnt sand dunes and the volcanic erruption on Island of Surtsey one that's in the book,
    literally 3 points..

    - algae lives on bare rock (pioneer community)

    - erosion of rock + build up of dead organisms makes enough soil for mosses + ferns to grow, they suceed the algae

    - larger plants then suceed these small plants etc etc

    Guess it doesn't hurt to learn it as it's not much (I know you probably have a book and could have read that yourself but it helps me too, to type it out lol)

    hehe I know it helps quite a bit answering people's queries
    the sand dune one has so many plant names, im not sure if we need to know all of them , ill jsut revise both of them jsut to be sure
