Adenine=Thymine/Uracil, Cytosine=Guanine

Today's lecture on Cell Biology was actually quite humbling.
Everything we do, how we do it, and why we do it is governed by our encoding. How we look, how we feel, how we laugh and cry and rage is all encoded in our bodies in the languange of DNA - Deoxyribonucleic Acid. Obviously, the mere act of communication in written and spoken form is quite complex, and uses 26 letters - all of which can be used to make a combination of over 200,000 words. And that's just so we can talk.
DNA must therefore be the most complex mother-fucking language out there, but guess what? It only has 4 letters in its language, in continuing the language analogy. 4 basic blocks, Adenine, Thymine, Cytosine, and Guosine.
How hectic is that.
Everything that every living creature and micro-organism can do is planned by these 4 building blocks. I know right, wtf? I don't need some fat frizzy haired lady leading a lecture to tell me how short of a miracle this is, but it gets even better.
A=T, C=G. One can only pair up with the other, and what astounded me the most was DNA replication - the process by which a double helix strand of DNA splits apart, and creates two daughter strands which are identical, this being possible only because one building block on the parent strand can only have one other possible pair.
Anyway, that's my nerd rant for today. There is a lot more that i could share with you, but there probably is no-one reading this and even if there were, you want to hear a bit more than boring crap about DNA right? So we go onto RNA! (Ribonucleic Acid)

Haha i'm just joking. Here is my day - a morning scenario group meet where i got a free muffin from Simren, who i think felt a compelling need to advance her brown-nosing from dominating class discussion to baking wheaten goods for the class, (jokes - they were delish), and where we started our first scenario. Immunisation!
The most boring and poorly-acted video in the history of UNSW was what aided us in a particularly debatable issue: the necessity of immunisation/vaccination of medical students. I'm looking forward to it, and i guess i better get started on my part of the "group effort", but i just cbf right now and dota is calling for me.
After an hour break, the lectures on cell bio. These were good. Very good.
After that, an extended chillout session at the uni bar playing - and losing - pool to Josh Kim, who i will never truly understand when it comes to winning pool under peoples' noses.
Yes josh, you will get your cheeseburger as promised. You north korean bastard.

Bye!
