How does the DNA data transfer itself throughout the cell? I mean, how does it affect the cell function when it is bound in the middle? Through telepathy?
ha ha good question ! but it transcribes the information to be transfered to m RNA which translates it to t rna which answers the info in the basis of protein !
sorry ... deleted without knowning whats happening ... seems as if my post went into another page and everything ... anyways; my point was that i didnt get what you just said ... bother explaining?
ok ! the information is travelled from dna to rna then to another kind of rna which puts it as proteins ! protetins are the information languages result ! u can look at these process in youtube ! type transcription, translation ! ok ?
another small question? ... how does the DNA know what it needs to say to the cell? There is another mode of transpost back to the DNA to let it know that its wrong decisions are making the cell die or sumfin' :D
yea there is a mechanism for that too :) which is way to commplicated which i didnot understand at school ! i would tell u when i find out ?
The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and concentration of metal ions, as well as the presence of polyamines in solution.
When a few gene in one cell become damaged, or mutated, this can lead to cancer. These faulty genes, or gene mutations, may tell the cell to multiply at the wrong time, or in the wrong place. This is how cancer starts. Sometimes the cell-cycle checkpoints themselves are faulty or the damaged cells are able to side-step them.
Q: how does the DNA know what it needs to say to the cell? A: We need to remember that an animal has the same DNA in each cell of its body, but different parts of the DNA is being used in different cells. There is a team of various molecules in the cell which control which portions of DNA is used. We say that these molecules "control DNA expression". Most of these molecules are proteins. Some proteins, called histones, cover up parts of DNA -- they hide the DNA from being used. Other proteins stretches out DNA and makes it easier to be read. These proteins are called transcription factors. All of these proteins, however, respond to some signal in the cell. Some proteins react to calcium concentration, others react to the presence of small metabolites in the cell. When you drink Coca-Cola, proteins detect that there is a too high concentration of sugar in your blood, and then tells other proteins to "turn on" the part of the DNA which has a gene for insulin. Insulin helps you lower the amount of sugar in your blood. Thus, it is a team of proteins which helps to control what portions of DNA is being used. Now, where do these "DNA-controlling" proteins come from? They were created from instructions written in the DNA! Most cell activity, actually, involves making more of these "DNA-controlling" proteins. So in the end, we say that everything depends on the DNA.
