About DNA

Popular, it is an in vivo gene transfer to another organism or species of organisms of different species in the process. In general are genetically modified through the sexual reproduction process of implementation. For example, plant pollen (containing male gametophyte) through various media by a plant, "run" to another plant, or "run" to a plant with another variety of the pistil inside the flower (containing female gametophyte) and on its hybridization, this hybrid process has resulted in the transfer of the gene. Similarly, for example, in cats that animals of different varieties and types of cats to mate with their parents after a not - kind of offspring is produced because of the transfer of genes. Therefore, the transgenic nature are every day at what is happening, but in nature, not the target of gene transfer, good and bad genes can be transferred to a different biological entity. At the same time, through natural hybridization for transgenic are strictly controlled in the same species (especially in animals), or very close genetic relationship between plant species.

There are mainly worried about eating genetically modified foods bad for human health, but personal opinion, eating the food might make to enhance human immunity, enhance human qualities, because hybrids do better than purebred.大众,这是一个在体内的基因转移到另一个生物体或物种的生物物种在不同的进程。一般转基因通过有性繁殖的执行过程。例如,植物的花粉(含有雄配子)通过各种媒体的一种植物, “运行” ,以另一种植物,或“运行” ,以植物与另一品种的雌蕊内花(含雌配子体)和其杂交,这种混合过程中造成的转移基因。同样的,例如,在猫科动物,动物不同品种和类型的猫进行交配后,他们的父母没有-种的后代,因为生产转移的基因。因此,转基因的性质是每天都在发生的事情,但在性质,而不是目标的基因转移,好的和坏的基因可以转移到一个不同的生物实体。与此同时,通过自然杂交转基因是严格控制在同一物种(尤其是在动物) ,或非常接近的遗传关系的植物物种。

主要是担心吃转基因食品对人类健康不好,但个人认为,吃的食物可能会提高人的免疫力,提高人的素质,因为杂种比纯种做得更好。
