number of people was 310  ;D
the easiest question was the one about tumours, it was lovely  ;D
and what did u write for the von bla bla factor question where they said use ur knowledge of the blood clotting process???

and the one abotu cystic fibrosis, there were 2 questions,
one said how a gene mutation results in ......
and the second was why ppeople infected with cystic fib. will be infected with this bacteria rather than people having no cysticc fib.
lol i wrote sum crap in that answer

lol yeh the tumor one was good and so was the 5 mark question about cystic fibrosis that was good about why mucus gets trapped in the airway
i seriously hated that question with the blood clottin it was annoying
i wrote about excess fibrinogen being converted to fibrin and formin a clot where the van ..watever was stuck

watch out for the biodiversity issues,drug trialling and stem cell therapy questions
also ecology variation and natural selection questions can be pretty tricky
other topics like plants reproduction and cells are mostly easy

ooooooook thanks for tryin
ill just write coding strand and not even mention sense or antisense lol

i read it in the book, its called the anti sense strand, which acts as a template for the coding of the mRNA. By the way,wats the enzyme called for DNA synthesis ? DNA Polymerase or DNA Ligase or DNA Helicase, cause i read about this some where which says that any of these three can b written :S  ???
