    CAN SOMEONE FIND OUT IF THIS IS TRUE PLEASE https://twitter.com/biology267383
    Whether it's true or not, no questions are shown. Doesn't help us either way, although if AQA get word…

    Any ideas for what to write if the essay is?

    -the functions of nucleic acids
    -factors which influence the concentration of glucose in the blood
    -the process of diffusion and its importance in living organisms
    -factors which determine an organisms phenotype

    Unless you were some geneticist there's probably not much out of spec stuff

    i've got essays on cycles, shapes fitting together, membranes and their functions, exchanges with external environment and importance of proteins and CO2 all having been marked as 19-21 if anyone has any different titles would be appreciated! for a swap

    Any ideas for some out of spec stuff for a DNA essay?
    Hii,

    On the BBC news lately there is this thing about 'CRISPR' that forms a part of a bacterial DNA.
    when a bacteria is infected with a virus, the bacteria has short palindromic repeats of DNA pieces that are complementary to the DNA of the virus.

    They use these repeats to make RNA molecules that bind to the viral DNA.

    Then a 2nd piece of RNA is made from the repeats of DNA interacts with a protein

    the protein will then cleave the virus DNA and inactivate the virus

    Researchers can use this techniques in Gene therapy to knock out specific genes

    I hope this helps!
    its been on the news for a While.....which is why I think that DNA may come up as a 25 marker

    all i can think is some genetic diseases not given to you i.e. not sickle cell or cystic fibrosis.
    how certain mutagens affect the DNA?
    discovery of human genome/pcr machine?
    idk not much you can know without doing loads of extra stuff and who tf has time for that when you need to know u1 and 2 as well :/ :')

    My biology teacher said that as sickle cell and cystic fibrosis actually aren't mentioned specifically in the spec and are given as examples you can gain synoptic marks for it.

    Also - if you do chemistry, you can get out of spec marks for hydrogen bonding apparently.

    Yea sickle cell anemia, SCID and CF all count as 'content not on the specification' and therefore count as additional information

    Me!
    I've got negative feedback, DNA in science and technology or importance of water?

    So guys

    So guys here are Pollock's Predictions, shall we plan them?
    Spoiler:
    Show
    - transport and exchange systems; the importance to the organism.- ATP; why is it so awesome? (Maybe better worded) (His words, not mine)-carbon dioxide, and its role in Biological processes-The many roles of inorganic ions-The many functions of concentration gradients

    What would you write for 'many functions of concentration gradients'?
    Synaptic transmission
    Sodium potassium pump -
    Maintaining resting potential
    Diffusion of IAA
    Active transport in the small intestine
    Oral rehydration solution - vibrio cholerae
    Diffusion through the membrane - maybe mRNA into the cytoplasm through the nuclear pore?
    Diffusion of hydrogen ions through ATP synthase in the electron transport chain
