Scientists found that in addition to the DNA genetic code in addition to the new password

According to Taiwan media reports, the United States and Israel scientists believe they have DNA (deoxyribonucleic acid) in addition to the genetic code to find outside of the second password. The newly discovered password ─ body responsible for deciding on the nuclear DNA that is the miniature protein spools around ─ the location. These spools at the same time protect and control access to DNA itself.
This finding, if confirmed, could open the control of gene related to higher-order bit of the new mechanism. For example, every human cell to activate the genes it needs but can not touch on other types of cells used in gene and so is also the key to the mysterious process.
Israel's Weizmann Institute of Northwestern University and saqr the Witton and his colleagues in this "natural" scientific journals, the author describes the DNA of this new password.
Every cell in the human body has about 30,000,000 nuclear body. The reason why it has taken so many nuclear, because the DNA-coated line for each of a nuclear-only. 65 times on each of the DNA helix that contains 147 units, and a single chromosome's DNA molecule at length on There may be up to 225,000,000 units.
Biologists suspect that over the years, DNA on some of the locations, in particular, DNA is most likely to bend to those locations, other than the location more conducive to the existence of the nuclear body, but the overall pattern is not obvious. Today, the witton Dr. saqr and analysis of the yeast gene location within about 200 of the series, knows these are entangled with the nuclear body, found two really implied the existence of a pattern.
Through the understanding of this model, they predict the success of other organisms into some five nuclear body. This model is easier to allow DNA bending, as well as the close of the package review body combination of the two series. However, in this mode, the Each nuclear-entangled only the location of a number of sequences can occur, it is not clear. It is precisely because of its loose formation conditions, it does not conflict with the genetic code.
