    some keyword definitions:

    Recombinant bacteria - is a microorganism whose genetic makeup has been altered by the deliberate introduction of new genetic elements. The offspring of the altered bacteria also contain new genetic elements.

    Atrophy - the decrease in the size of any organ caused by disuse or disease. Atrophy is caused by mutations/poor nourishment/poor circulation/disuse/lack of exercise

    Muscular dystrophy - a group of inherited disorders that involve muscle weakness, loss of muscle tissue which gets worse over time. Is a genetic [inherited] condition that gradually causes muscles to weaken

    Gene doping - the non-therapeutic use of cells, genes, genetic elements or the modulation of gene expression, having the capacity to improve athletic performance.

    Muscle biopsy - is a procedure in which a piece of muscle tissue is removed from the organism and is examined microscopically - shows how muscle fibres are damaged


    cheers bro! this is brilliant
    p.s wt about blood doping?

    gene therapy looks to alter the genes of a person with a disease to cure it whereas recombinant bacteria provide proteins (such as insulin) to help with the symptoms of the disease, not to cure the disease
    I think that's about right, that was the stuff I did most recently lol x

    Does anyone else find it wierd that the grade boundaries for the Jan 2011 paper are so much higher than the Jun 2010 paper? Even though the Jan 2011 paper is blaitantly harder than the Jun 2010 paper :/

    The long QT syndrome (LQTS) is a rare inborn heart condition in which delayed repolarization of the heart following a heartbeat increases the risk of episodes of torsade de pointes (TDP, a form of irregular heartbeat that originates from the ventricles).

    i think that this is because it was mainly private candidates and re-takers who took this exam so i guess you could say they all did particularly well!

    As above, but also, the June 2010 paper was the first paper of this course sat.
    These always have much lower grade boundaries to compensate, whereas we now have had 3 practice papers (including the specimen paper) and our teachers now know more to expect.

    Phytochromes are the photoreceptors in leaves, stem, root and shoot of plants.

    Pr is converted to Pfr in daylight, and Pfr is converted to Pr in night time.

    They control the flowering of plants (and germination of some). 'Long Day' plants will flower with a lot of Pfr as there is not much darkness so not much Pfr is converted back to Pr. 'Short Day' plants will flower with lots of Pr as there is enough darkness to convert the Pfr back to Pr.

    This means plants can flower in different seasons depending on the day length.

    There is also the fact that Pfr is changed back to Pr in far-red light, but that is unlikely to come up.
    Thanks man.
