    how much gene tech do people think will be on the paper, its very very confusing and very content heavy, can anyone summarise?
    Well DNA technology is the biggest part of the spec for Unit 5 so probably quite a lot. But then its AQA so who ever knows what they're going to throw at us

    Can anyone explain restriction mapping? and what is the point of it? like why do we want to cut up the plasmids at these specific recognition sites?

    Does anyone know what the AQA definition of kinesis is for certain?

    The AQA Nelson Thornes textbook says "...the more unpleasant the stimulus, the more rapidly it moves and the more rapidly it changes direction." (and vice versa)

    The CGP book says: "As the air gets drier (more unpleasant stimulus), they move faster and turn less often..." (and vice versa).

    A past AQA question from 2006 suggests that the CGP book is actually correct however other than that question there have not been many questions about kinesis.

    Yeah, just might be useful in the essay, I'm sure it won't matter loads though
    The amount they've put in for DNA Technology is too much haha
    I just keep thinkjng that they've had to rewrite the papers really quickly because they got stolen so it might not be very well writen or it might be really easy - fingers crossed

    Good luck!

    Which may mean that kinesis is more likely to come up on our exam... :/
    But how are we supposed to answer a question on it if there is no solid definition of kinesis?

    I've had so many things like that this year when different books contradict wiht each other. I tend to go with what it says in the AQA textbook because they've endorsed it.

    Whatdo you think might come up this year based on what hasn't come up in the past papers?

    Yeah I asked mine and he said that he didnt hear about it but the exam could possibly be easier, which would be awesome!

    the organisms movement is effected by a non directional stimulus- this is in the revision guide, i always say random movements too

    my teacher said these, she gave us a list
    Reflex arc
    Eye - distribution of Rods and Cones – sensitivity and acuity
    Kinesis
    Pacinian Corpuscles
    Myelin Sheath /speed of transmission of action potential
    Synapses (only covered briefly)
    Regulation of Body Temperature (only covered briefly)
    Transferring genes from one organism to another using plasmids as vectors (only covered briefly previously
    )Identifying transformed organisms -
    Replica Plating
    PCR
    Transcription and Translation – detail of processes
    Sequencing Genes using Sanger Sequencing
    Electrophoresis (only covered briefly previously)Probes (only covered briefly previously)
    DNA Fingerprinting (only covered briefly previously)Uses of transgenic organisms

    wow thank you so much for writing all that out. I don't feel like I know enough about Pacinian corpuscle other than stretch mediated ion channels or rod cells etc actually.
    I definetly feel like they've hardly done much an transcription translation so I hope that comes up.
    How are you feeling about the essay? I haven't done much AS stuff bc I haven't had the time :s

    no worries haha, yeah im not too keen on pacinian corpuscles, the eye(but thats not too hard to go over) and dna tech
    i think theres not much more i can do about the essay, as long as i read the question and do a good plan, i resat unit 1 and 2 so i'm okay on AS knowledge i think, just go over basics and recurring topics good luck!

    I'm literally just learning mitosis, meiosis and cell organelles, I don't have enjough time now to do anything else. Lots of people reckon DNA might come up as essay question

    Sounds like a good start, I really don't have time to do other units either so hoping key topics would help make me prioritise my revision

    Hi, I was just wondering have people learnt about Cystic Fibrosis and SCID as exaples of gene therapy etc
    It's in the AQA T&T text book but the speciifcation literally just says

    ' The use of gene therapy to supplement defective genes' and Candidates should be able to evaluate the effectiveness of gene therapy

    So do I need to learn the specific examples of Cystic Fibrosis and SCID or not?
    Cystic fibrosis is technically on the spec so apparently can be counted for as the off spec. information on the essay! Worth learning
