Understanding DNA
There are four naturally occurring bases in DNAAdenine, Thymine, Guanine, and Cytosineknown as A, T, G, and C.

stuck in our memories from year 10 science ?

isn't that a bit dodgey? i mean it's amphiprotic, non?

caffeine is one
and
methylamine, (CH3NH2) which is the stuff that gives fish the rotten smell....thats why people put lemon on it(lemon-citric acid that neutralises it)
nicotein is also one

wow good stuff....thanks

regardless, it is still a base, who cares if it can also act as an acid

You guys forgot urasil... it's in mRNA... wish I had actually been asked some questions which used this Bio knowledge I have stored away... I hope they ask bio questions in the chem exam lol.

Hmm... I used HCO3, it should be fine.

'Uracil'. btw, if you do bio next year then you're almost set for the exams already so I'm led to think.

Bah, our chem exam's on monday (followed by bio, maths, physics, maths, more maths). So much organic chem...
most clear cut experience was that conc sulfuric acid BURNS, and VERY quickly.

don't use HCO1.. mee agree with Frigid... it's too dodgy since it's amphiprotic.. just use blanky CaCO3 will ya? That's the best blanky thing in this whole blanky 30 something posts lol.. if you used lake as your buffer then you should remember this.. hmm... okay.. back to the point ----> they WON'T blanky ask use about a naturally occuring base (i think someone mentioned it before..) IT'S NOT BLANKY SPECIFIED IN THE SYLLABUS FOR CHOCOLATE'S SAKE (well.. not in the cores and shipwrecks)

better stop my blanky blanks.. lol Good Luck everyone ---> even though you mightn't be reading this before the exam
