    1. Explain how RNA interference affects the expression of a gene

    Muscle fibres may become torn and damaged. Damaged muscle fibres have an increased messenger RNA concentration and a higher rate of oxygen consumption, at rest, than undamaged muscle fibres.

    2. Explain these observations:
    increased mRNA concentration....
    higher rate of oxygen consumption...

    My exam board is AQA but my teacher gave us these questions from OCR to do, but I can't seem to find anything in the textbooks, does anybody have any pointers?

    Thank you
