DNA/RNA etc

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 :smile:
