Aye, so stuff like the sequence of events in atherosclerosis, all the BMR and energy stuff, advantages and disadvantages of using BMI and the other measurements.

Great, that saves me a bit of time! Thank you.

I was just about to ask for the 2002 answers..I hope someone has them, just done the whole past paper then realised that there wasn't a marking scheme :frown:

I also have a feeling that the essay will be on succession or regulators and conformers!

Well like a few people have said, I was thinking it might be something along the lines of succession or regulation/conformation. I think I could manage succession but I really don't like the regulation and conformation stuff - I wrote an essay on that in the prelim and got 7 :colondollar:

I would love a niche and competition essay to come up but since that was an option in 2012, I think the chance of it is very, very slim :redface:

I also wouldn't mind something about intensive food production either, because there's just so much to write about.

Yeah, succession or regulation/conformation seems to be on the minds of quite a few people at the moment.

Really hope it's a unit 2 essay. Unit 2 is so much more straightforward I hope to hope its mimicry, symbiosis or dormancy

Can somebody please describe physical mapping, and what BAC and YAC are ? I'm so confused with DNA technology, it's the only topic out of the whole course that I'm struggling with :frown:

Physical mapping is used to determine the order of genes on each chromosome and the number of base pairs between each one. What i think they do is use a number of STS (sequence tagged sites) these are specific base sequences that are only found on one single place on the genome, so if you probe for that specific sequence you only bind to the desired place on the genome. These act as sign-posts to determine where certain genes are on the genome and the number of base pairs can be counted between each one. Giving more detail about the physical map. Hope this helped, sorry i have no idea what BAC and YAC are.

Symbiosis would be a dream come true!
