"In vertebrate cells, the methylation of cytosine seems
to provide an important mechanism for distinguishing
genes that are active from those that are not.
The methylated form of cysteine,
5-methylcytosine (5-methyl C),
has the same relation to cytosine that thymine
has to uracil and the modification likewise
has no effect on base-pairing.
Consequently, a simple mechanism permits the
existing pattern of DNA methylation to be inherited
directly by the daughter DNA strands.
An enzyme called maintenance methyltransferase
acts preferentially on those CG sequences that
are base-paired with a CG sequence that is
already methylated.
As a result, the pattern of DNA methylation
on the parental DNA strand serves as a
template for the methylation of the daughter DNA strand,
causing this pattern to be inherited directly
following DNA replication."
you know, i used to think it was ultimately cool
that i got a chance to study all this.
i mean, to be honest, if information was spoon-fed
to you, its bloodly interesting.
otherwise? like PBL systems? its fucked up.
those paragraphs are EASY. wait til you see the diagrams.
i wanna cry just looking at them. it takes so much brain work
that i fall asleep staring at them! zz.
and my classmates arent helping. i tink they actually..
understand this shit.
and i feel kinda out of place.
theres a fat bitch in my group, she looks like those
church freaks. the kind that doesnt know what a handphone is.
well i compiled the powerpoint slides for my team,
cos i dint really do ANYTHING,
and she dint do anything either.. so what does she do?
she REARRANGES WHATEVER I ARRANGE.
talk about trying to make a point.
i dont know if i was more angry or irritated.
or sad even. gees.
seriously?! i mean i arrange it to give the presentation
some sort of a 'flow'.. and SHE comes and un-does it
and my teammates were like "Huh? wasnt cell determination
before cell differentiation?" zz. x2. -.-
my right eye is kinda spasming on me now
its being stupid cos my eyes are dry and tired.
and i rub it and it tears. so i look like im crying,
in one eye.
gonna wait to go smoke soon. then make my way to town.
baby, sorry i was kinda a bitch this morning,
im real tired, and i was slightly grumpy. you being
grumpy too dint help both of us either.
but i tried to calm myself, and make sure i wasn't
being unreasonable. hugs.
okay. gonna go now. before christine calls me-
chaos
