how can DNA....

Postby baikuza » Tue Aug 30, 2005 10:51 am

how can DNA which is just a combination of nitrogens, carbohydrates, protein can control our cell?

any one gime the answer.

Thanks

Mm...
let me think..
i don't understand why DNA or a combination of atoms can make a big effect to the cell.
nucleus control all activities in cell(e.g when an organel cell active more then the others, nucleus allways near with the active one. but how? how it control the organel. is it talk or something like that or what)
you know it just a small combinaton of molecules in nucleus.

You're trying to define how life works. It was a big leap when organic molecules became life. After all aren't cells just a bunch of chemicals? The answer is probably extremely complicated or not yet discovered. If it has been, intrepid scientists like MrMistery would be whipping up new species like cotton candy.

may be i'll go there. but, it's a long journey.
I wonder may God give me a mirracle then I can describe it.
You know, Everybody has a dream and they're hoping to make it come truth.
well.. I'm still want to know. this is my desire
and i will very happy if someone help me to do that.
or my ego will control my self to do that even I know I won't able to do it by my self

____________________
wanna know the fact.
wanna get the answer
I feel so thirsty of knowing the answer of my questions
is my brain can hold this?
can I to make it truth?
..... still wondering

Ok, so here is the basics of basics of basics.
Our methabolism, and life in fact consists from milions upon bilions of chemical reactions happening with an enormous speed and accuracy. All of these chemical reactions, those outside the cell as well as those within it, are directed by enzymes and hormones. DNA contains genes, each gene codes for a specific protein. Each protein(and i am talking about enzymes here) "oversees" a specific chemical reaction. So, DNA controls everything that is happening in your body through these proteins(MAINLY!)
To put a lot more simply than it really is...
Have a look at a molecular genetics book on nucleic acids

Andrew

mm.. :idea:
so DNA using his codons to make protein (e.g hormones, enzymes) to control our body.

OK.. thaks for this.

hei, I have a question
ribosom makes the proteins(amino acid) for dRNA. it connects to dRNA by a random moving such as the enzymes do(like lock and key)?

_____
now i know ..
hm.. feeling good
:) why i don't thinking to there.

Actually DNA controls our all by generating triplet of codons which is transcripted to mRNA and then to the rRNA to generate amino-acids. Then these amino-acids (consist of 20 amino-acids) will form protein by forming peptide chains or disulphide chains. I think that all of these proteins who are controlling our life (because there would be no life if there are no metabolisms). But, since the basic former is DNA, then DNA is said to be the master of life.

I think tou typed dRNA from Indonesian words eh?(RNAduta)..actually it's mRNA. In order to form amino-acids, mRNA have to give their triplet codons to rRNA and then rRNA will form amino-acids from the 'pool' in Ribosome.

ok... that's right. dRNA taken from indonesian word... :shock:

yo.. thanks.
