Theoretical Core of Genetically Medicine - Mendel Genetic Law - Some of the silence of wild grass. These wild grass have inherited the DNA who did not inherit their parents in a certain way. This is impossible. The traditional view is that the genes are transmitted in DNA, and all organisms must accept this parental genetic and mutation. The chemical or structural change of DNA may close the gene, and these changes will be passed down, and this phenomenon is called after genetic modification. However, the post-late change has not changed the actual sequence of DNA. This situation seems to appear in the model plant of genetic studies in the biologist - in Neule. The medullary of two mutant copies with a gene seems to be able to correct the DNA they pass to ensure that at least some descendants will return to normal. The research team leaders in the Leaders of the University of Porida University in this discovery that they have repaired the mutant gene from the RNA template from the ancestors than the parents. Maybe this phenomenon will only appear. In this plant. But the Pluject Study Group issued a papers in the "Nature" magazine, which may be a more common mechanism that allows the plant to maintain RNA as a backup while "try" new mutations. If the mutation is harmful, the next generation of plants will restore the DNA sort of their grandparents with the help of RNA. Proudit said: "This is really reasonable." This mechanism is especially useful to the plants of the flowers, as they are not like other plants. But they may exist in all plants and even animal species. The Putuit's research team has this finding because they find some Arabidopsis to refuse "faithful reproduction". In the experiment, although the two copies of a gene in the Arabidopsis parental strain have caused a mutation of the petal lotion, but in their next generation, there are still about 1/10 of plants to grow normally. Putuit is very annoyed. He thought that it was mixed with normal seeds or pollen in his own experiment. However, a series of experiments exclude pollution and other various possibilities. Eventually there is only an unbelievable explanation: these normal offspring have obtained genetic information of the ancestors above the parent. Prolid said: "It must be recognized that this phenomenon may be limited to this gene. But I think this is unlikely."
