09-06-2012 20:50 The telomeres and telomerase Medicine 2009 Nobel Prize in physiology telomer khavinson npcriz peptid bioregulators The telomeres or telomere of the chromosomes forming DNA at the end of short, repeated thousands of times more sections, which are about protecting them from destruction, from falling apart. TTAGGG in humans and mammalian animals the code is repeated thousands of times, this sequence represents approximately 20 to 25000 base pairs. The cells (and thus the whole organism) élettatalmát determined. Each nucleus of somatic cells with 2n, ie, 46 pairs of chromosomes in this organism as a whole make up the DNA molecules encoding can be found. Shorter or longer cells are divided in sections (except for example. The nerve cells). This genetic material to be kett?z?dnie (S phase). Each doubling of the chromosomal DNA after a few base pairs shorter. The amount is about. 100 basis, because the DNA is responsible for copying the operating mechanism of DNA polymerase enzymes. While the non-coding genes teloméra shorter section of DNA is not damaged, the longer is the region's more teloméra division failure can occur without damage and it's easy to see: that much longer we can live as healthy cells. The human cell is about. 50 are able to divide, after which the DNA damage is significant. More bad news is that the chromosomes without telomeres are not protected from damage anything, so they may be linked to each other, resulting ...
