You are alive because of mitochondria in your body Bashny.Net

It is believed that the human body are all very harmonious, but even now in our cells have a completely alien elementy



Mitochondria are swimming in the mucus your cells and constantly make molecules which move your body. But before these mitochondria were independent of your body: they were bacteria in the outside world. So you're at a fundamental level - the result of symbiosis, the result of the interdependence of the two forms of life.

Mitochondria produce energy for our body. Floating in the cell cytoplasm inside the cell, but outside the cell nucleus, they are working, producing adenosine triphosphate, or ATP. ATP is used as a source of energy that occurs when a substance is decomposed into individual components. The energy you need the time, the mitochondria, and its provide. These organelles are so important that they even participate in the process of fertilization. Mitochondria in unfertilized oocytes swim, waiting sperm.



In mitochondria have their own DNA, called mitochondrial or mtDNA. And mitochondria can reproduce itself quite apart from any deoxyribonucleic processes occurring within the cell nucleus. Since mitochondria have their own DNA, and they do not need fertilization, when it comes to breeding, you - a clone of your mother. In your cells, it mtDNA and mtDNA of her mother and her mother's mother's mtDNA, and so on. D. That's why mtDNA is so much interest from scientists geneticists. Sometimes it can mutate, but it is not like a normal DNA inside the cell nucleus. The fact that there is a separate mitochondrial DNA, it is certainly strange. But this circumstance pales in comparison with the form of DNA. Mitochondrial DNA has a rounded shape. This spiral, are twisted into a ring. Mitochondria seem even more strange when you look at the barrier between them and the rest of the cell. Mitochondria are different from other organelles that have a double shell. Ring DNA double cell walls as well as the fact that mtDNA did not like the DNA of the cell nucleus, making mitochondria more like than human cells, and some bacteria that have put their own suits, consisting of a double cell membrane, and We plunged into our cells. Now scientists believe that the process of evolution was just that. This process is explained in detail modern endosymbiotic theory, which clearly proves that our cells could at some point, "shelter" parasitic bacteria, but do not swallow it, and began to use as an energy source.
