lol-"parrot thinghy's" :biggrin:

, anyway, i put down check for hereditary diseases and make sure they are not from same gene-pool, to prevent inbreeding.

My mum is in the same as me and your sig is getting me dodgy looks :P

-Cigarettes contain carcinogens
-Cause mutations in DNA of cells
-in the lining of the lungs
-cell populations divide rapidly
-by mitosis
-they become a malignant tumour
-block off large parts of the lungs

That's what I got. Doubt it's worth the full 6.

I put cell multiplies instead of divide :frown:

Yeah, an odd choice for a 6 mark question.

I'm not sure what else you could've said for that question. There's barely any theory covered in the textbook.

Yeah thats what i thought
I did all the carcinogen talk blah di blah and how it enters cells and disrupts the genetic mechanism etc and uncontrolled replication.

I then talked about experimental evidense backing up the link to smoking with cancer such as the mice and then talked about epidemiological evidense and said referring to figure 1.5 since they gave the graph for us ^_^ LOL it was worth another mention, i was trying to write anything lol

stop reminiscing over an exam and revise chemistry for tomorrow

stop this, you're making me sad and unhappy, i'm just going to sit here drawing boltzmann distribution and enthalpy profile diagrams till my hearts content (and protend that we don't need to learn anything about resources or mechanisms)

Yeah, I was quite happy with the way I tackled that question and the 7 marker on DNA.

yh i put all that malarcky about double helix untwists, then unzips etc......I hope thats right!!! lol

Well, I think the words they were looking for were uncontrolled replication, but divide and multiply will probably be accepted too

I cant!!! lol

all i can think about is this blumin exam.....................

and I also hate the fact they make us wait so long for results.....

I dont know about that, i think for cancer the replication is more specific, e.g uncontrolled cos thats when it can be classed as cancerous.

But i dont know about the mark scheme so who knows

I put glycogen is insoluble then decided it was soluble in the last 5 minutes T_T

Damn and blast.

It wasn't nucleotides, it was 'nucleic acids'.

I thought of it the other way round, I thought nucleic acids first, then I remembered lipids. Will be pissed off if I lose the mark.

That question didn't have the option 'phospholipid' though? With just lipid, it could relate to a range of oils or fats. I put nucleic acids, I may be wrong.

For the Tamiflu one it doesn't matter which way you put it as long as you explained a method of inhibition

well if its any consellation.....the question was asking for structure.....so it being soluble or not has nothing to do with it...........

btw you are talking about that "compare collagen & glycogen" question arnt you....???

I thought that this paper really lacked a lot of theory, I was disappointed. I know that some content is inevitably ignored, but there was little on the immune system, biological molecules, bonds etc!
