The yeast and worms

The yeast and worms, simple biological evolution is how to birds and mammals such complex biological? A study conducted comparative genomics research shows, widely the answer to the problem may be hidden in the biological waste deoxyribonucleic acid (DNA). The scientists found that the more complex biological and its carrying the junk DNA, and the more they didn't code "useless" DNA help higher evolution of the complex.
Since the first eukaryotes -- including from yeast to human nuclei creatures -- since to be interpreted genome, scientists have wanted to know why, most of the DNA and no biological form useful genes. From the chromosome mutation protection to support structure for the so-called junk DNA could explain a lot of. But last year from humans, mice and rats of identical about junk DNA results show that in this area are important may include the regulating mechanism, which can control the basic biological chemical reactions and development process, this will help evolution of a more complicated. Compared with simple eukaryotes, complex organisms have more genes mutating will undoubtedly the greatly strengthened the fact that this one.
In order to this problem by a deeper understanding of the university of California, Santa cruz, UCSC (David) calculation biologists Haussler research group, a leading to 5 kinds of vertebrates -- people, rats, mice, chicken and the junk DNA sequences blowfish, with four insects, two worms and seven kinds of yeast junk DNA sequences are compared. Researchers from the result of an astonishing mode: the more complex and more important to junk DNA.
The possibility of implicit in different kinds of creatures, if you have the same DNA, so these will DNA is used to solve some key problems. The yeast and vertebrate sharing a certain amount of DNA, after all, they all need to manufacture protein, but only 15% of DNA and gene were not. Study group on July 14 of the human genome research magazine reported online, they will be more complicated with yeast compares the worms, and the latter is a multicellular organisms found that there was no 40% of the DNA encoding. Then, researchers will again be vertebrates and insects, and compares these creatures are more complex than the worms, and found that, there were more than 66% of DNA contains any code of DNA.
Participate in the research work of Adam biologists Siepel UCSC calculation, the research results about the worm, which is seriously need for them because scientists just two genomes are analyzed. Nonetheless, or think, this Siepel strongly support that such a theory that vertebrates and increase the complexity of biological insects is mainly due to genetic regulation of fine mode
