Oh nice, we started with how genes get fucked up, types of mutation and normal DNA processes.

It's still a long way until we start with syndromes and diseases, but I learned last class how exactly Down syndrome gene gets altered.

 

Chromatin X, I read it but didn't understand it that much, all I could understand is that it's only visible on women and that only one X chromosome gets activated while the rest get inactivated.

Also something about Klinefelter syndrome kids having it present while Turner syndrome girls don't have it.

I think genetics is... interesting :sad:

It is, but I personally find it annoying to read. All the gene sequences, and the language is more complicated. I guess I need to get used to it.

^^Yeah, but it becomes so fucking hard!

Oh I see exactly what you're talking about!

So, since there are 2 X chromosomes, only 1 must be active otherwise everything is fucked up. The other one is desactivated due to a gene which is on this chromosome (XIST I think :thinking:), so it becomes all shrivelled so the genes can't be active anymore, and that's what's called chromatin X!

 

Klinefelter is XXY, so they must have one X desactivated, but Turner is XO, so the only X needs to be active.

Did you understand something? :uhoh:

Wait, you mean like, correct activation to get the right sexual sequence like:

XX and XY?

Yes, it's XIST.

OH GOD I LOVE YOU :stunned:

Yes ! :D

Haha I'm glad I helped, and I'm proud of me cause it's 2:30am and I drank a little before ^^

 

So that's it, but it's still pathological since some genes on sexual chromosomes have to be active on both (on pseudo-autosomic regions), and these genes are active 3times in Klinefelter, and only 1 in Turner!

 

Bye bye I'm going to bed! Night night :kiss:

Night Perrine :nice:

Yeah, I remember that too. But again, too complex, I hope the doctor can explain that tomorrow.

You did great, thank you very much :heart:

If I become a lead forensics investigator (or LFI as Vince Masuka calls it) maybe I'll be happier since dead people can't die.

Unless they're zombies. Then they have to be re-killed.

Then I'd kill them viciously with my set of scalpels and electric chainsaws.

I would hope so.

 

I'm going to bed. I have to wake up and take 2 tests tomorrow.

Night Nick. Good luck with those tests.

Alexa shouldn't be unhappy, it makes me sad :(

Sorry Eddie, but right now it's impossible for me to feel anything remotely similar to happiness.

Ah well, it'll get better?

Probably never. All I know is that I have to cry all the shit I didn't cry these past few months.

:(

That sucks but just...I don't know :bigcry:

Don't worry. I'll stop crying eventually.

Ugh, shit life is shit. Not really helpful coming from a random stranger on the internet but good luck. :hug:

Thanks.

Yes, shit life is shit.

God this is annoying.

I cried all night, and I've been crying for the past 20 mins. Weird cause I never cry.

So, did you understand that better today? :wacko:

Aww thank you :blush:

 

Btw, why did you change the title of this thread? It's not true:whip:

 

Oh, and I gave some blood today finally! And I wanted to look at the big needle when the nurse put it in my vein, i'm weird :uhoh:

I understood today :nice: She was really careful explaining it, and I got it.

I changed the title cause I used to feel amazing by the fact that I'm a med student and I'm studying to have one of the best jobs in the world, but I dunno, maybe it isn't special at all. Maybe I'm still common like the rest of the world. Yay for me..

 

Blood for what? Biochem? :wacko:

I'm giving blood again tomorrow, for glucose test. Did you take some blood? :D

 

I had an anatomy test today, easy :heart: And I started doing some problems in biochemistry, pH.

I DISSECTED A HEART TODAY, IT WAS AWESOME
