At
present, one tenth of the gene ditribution comprising three billion letters
have been analzed. Several things have revealed: P-53, consisting in the seventeenth
chromosome. In the protein P-53 produces is P-53protein. It has turned out to
be the controller of the advance of cancer.
What on earth the work of P-53 protein's work like? P-53 protein behaves as if it were an ambulance in human body. When it finds a fire, it calls its partners, and urge thm to be careful for the metastasis of cancer cells. This is the work of the metastasis of cancer cells. Then, what stops the work of P-53 and trigger the incidence of cancer? Smoking is i\one of them. Cigarettes include a ferment, benzophyren, by which T-53 and increase the incidence of human. And surprisingly, even the ultraviolet rays from the sun has an unfluence on p-53.
UV from the sun destroys P-53 when it reaches to P-53 and cause skin cancer. By the way, each cell of human body has to copy the same DNA as each has because of metabolism. In these huge quantity of copys, some miss copys are caused accidentally.
It is known that P-53 have something to do with the generation of more than 50 types of cancer, six tenths of known cancer.
Thanks to the analyses of genes, closer cause of disease can be helped and it helps thrapys grouws, due to which we get the development of medical science and live with more confidence.
Gene analyses are about to enable us to diagnose by checking genes. We do not have to go to hospitals. All we have to do is insert the CD-ROM of your genes' information into your computer. You do not have to go to a hospital to wait your turn, and after a whole day's wait do you see a doctor only for three minutes. One of those example is "DNA chip". AFFYMETRIX, Inc., Silicon Valley, Calofornia, America, developed "Gene CHIP P53". In this chip, the design of one side of P-53, thus if a patient's design's one side is checked by irradiation of laser, cancer can be prevented, treated early, or cheked before he or she gets sick.
The time has come when one's computer shows massage like this.
We call one twentieth of whole DNA information designing human beings, which can produe protein, "Exon". The other nineteen twentieths can not produce protein at all, which is now pointed, because in this information is the weckage of various viruses which human beings have ever caught.
@So to speak, the latter is the remains of human beings in the past. Every life, whether it is an Elephant or a plant, has DNA namely, human genome project are capable of becoming the key to elucidate the history of life by using the viewpoint that can trace the history.
